Applied Linguistics: Glossary

 

A Comprehensive Glossary of Applied Linguistics

Undergraduate and postgraduate reference guide | Definitions, explanations, examples, theories, methods, and applications

Applied linguistics is a broad, interdisciplinary field concerned with understanding and addressing real-world problems in which language plays a central role. These problems include language teaching and learning, multilingual education, language assessment, translation, professional communication, language policy, literacy, language disorders, forensic investigations, and language technologies. The definitions are designed to be accessible to undergraduate students while retaining sufficient conceptual precision for advanced study. Examples are included wherever they clarify a distinction or illustrate a term in practice.

Part I. Foundations of applied linguistics

1. Core concepts and the scope of the field

1. Applied linguistics

The interdisciplinary study of real-world problems involving language and the application of linguistic and related knowledge to understand, investigate, and address them. It draws on linguistics, psychology, education, sociology, anthropology, and other disciplines.

Example: Investigating why Pakistani university students can memorise English grammar rules but struggle to communicate fluently, then designing and evaluating a teaching intervention.

2. Theoretical linguistics

The study of language's structure, representation, and underlying principles. It investigates how linguistic systems work, rather than necessarily beginning with a practical problem.

Example: A syntactician investigates how pronouns receive case or how subjects are represented in sentence structure. Applied linguistics may use such findings to examine language development or teaching.

3. Interdisciplinarity

The integration of concepts, theories, methods, or evidence from different academic disciplines to investigate a complex problem.

Example: Studying second-language learning through grammatical analysis, cognitive psychology, classroom observation, and sociological research.

4. General linguistics: The systematic scientific study of human language, including its sounds, structures, meanings, use, acquisition, and variation.

5. Descriptive linguistics: The investigation and description of how people actually use a language or variety, without treating one variety as inherently superior to another.

6. Prescriptive linguistics: The formulation or promotion of rules about how language should be used according to a particular standard or convention. Prescriptive rules are common in editing, formal writing, and educational assessment.

Example: Descriptive linguistics documents the different forms of English used in Pakistan; a prescriptive style guide may recommend one spelling or grammatical convention for a formal publication.

7. Micro-linguistics: The study of internal linguistic systems, especially phonetics, phonology, morphology, syntax, and semantics.

8. Macro-linguistics: The broader investigation of language in relation to cognition, society, culture, communication, education, and technology. The term is used in different ways across traditions.

9. Language problem: A practical difficulty involving language, such as low literacy, ineffective communication, language-based discrimination, translation errors, or difficulties learning an additional language.

10. Language-related problem-solving: The process of identifying a language problem, collecting evidence, analysing its causes, designing an intervention, and evaluating the outcome.

11. Evidence-based practice: The use of systematically collected research evidence, professional expertise, and relevant contextual considerations to guide decisions.

12. Critical applied linguistics: An approach that examines how language practices relate to power, inequality, ideology, social justice, identity, and institutional structures.

13. Language awareness: Explicit understanding of linguistic forms, functions, variation, and the social consequences of language choices.

14. Language ideology: A belief or assumption about language and its speakers, often connected with social values and power.

Example: The belief that only one accent sounds intelligent is a language ideology, not an objective linguistic fact.

15. Linguistic discrimination: Unfair treatment of people because of their language, dialect, accent, vocabulary, or perceived language proficiency.

16. Linguistic repertoire: The range of languages, dialects, registers, styles, and communicative resources available to an individual or community.

17. Language ecology: The study of relationships among languages, speakers, institutions, social environments, and the conditions that support or threaten linguistic diversity.

18. Language rights: Rights relating to the use, learning, maintenance, and public recognition of languages. Their legal scope depends on the applicable constitutional and international framework.

19. Language planning: Deliberate efforts to influence language use, status, structure, acquisition, or institutional functions.

20. Language policy: Explicit or implicit principles and practices that govern which languages are used, taught, assessed, or recognised in a society or institution.

Part II. Linguistic theories and frameworks

3. Major schools of linguistic thought

21. Structuralism

A theoretical tradition that analyses language as a system of interrelated elements. The value of a linguistic unit depends partly on its relationships with other units in the system.

Associated scholar: Ferdinand de Saussure.

Example: The distinction between cat and bat depends on the contrast between /k/ and /b/.

22. Sign

In Saussurean linguistics, a linguistic sign consists of a signifier and a signified.

Example: The written or spoken form tree is the signifier; the concept of a tree is the signified.

23. Signifier

The perceptible form of a sign, such as a sound sequence, written word, or other linguistic expression.

24. Signified

The concept associated with a signifier within a linguistic system.

25. Langue

Saussure's term for the socially shared system of linguistic conventions underlying individual language use.

26. Parole

Saussure's term for individual acts of speaking or language use.

27. Generative grammar

A framework that seeks to characterise the grammatical knowledge that enables speakers to produce and understand an unlimited number of sentences from finite resources.

Associated scholar: Noam Chomsky.

Example: A speaker can understand a novel sentence such as The student who interviewed the professor submitted the report without having memorised that entire sentence.

28. Universal Grammar (UG)

In generative linguistic theory, the proposed innate component of the human language faculty that constrains or guides language acquisition. The nature and extent of UG remain subjects of theoretical debate.

29. Principles and Parameters approach

A generative framework that proposes shared grammatical principles alongside points of cross-linguistic variation traditionally modelled as parameters.

Example: Differences in subject omission or word order have been analysed through parametric approaches, although individual phenomena often require more detailed explanations than a single parameter provides.

30. Minimalist Program

A research programme in generative grammar that investigates how linguistic structure might be derived through economical computational operations and interface requirements.

31. Functionalism

An approach that explains linguistic structures partly through their communicative, cognitive, and discourse functions.

Example: A speaker may say The report was written by Sara to make the report, rather than Sara, the starting point of the message.

32. Systemic Functional Linguistics (SFL)

A theory associated with M. A. K. Halliday that treats language as a resource for making meaning in social contexts. It examines ideational, interpersonal, and textual metafunctions.

Example: Analysing how a scientific report represents processes, establishes authority, and organises information.

33. Cognitive linguistics

An approach that studies language in relation to general cognitive abilities, conceptualisation, categorisation, attention, and embodied experience.

Example: Expressions such as defend an argument and attack an idea reflect a conventional conceptualisation of argument as conflict.

34. Construction Grammar

A family of approaches in which constructions, understood as conventional pairings of form and meaning or function, play a central role in grammatical knowledge.

Example: The pattern She baked him a cake associates a syntactic construction with a transfer-related interpretation.

35. Usage-based linguistics

An approach that emphasises experience with actual language use in shaping linguistic knowledge, including frequency, analogy, categorisation, and entrenchment.

36. Connectionism

A family of computational and cognitive models in which learning and processing emerge through networks of interconnected units whose strengths change with experience.

Example: A model may learn patterns in past-tense formation by exposure to many verb forms.

37. Post-structuralism

A broad intellectual tradition that questions fixed meanings and stable categories, examining how meaning, identity, and knowledge are shaped by discourse, history, and power.

38. Functionalism versus formalism

Formal approaches prioritise the structural properties and computational organisation of language; functional approaches emphasise how structure relates to meaning, communication, cognition, and use. In practice, many researchers combine insights from both.

39. Descriptive adequacy

The extent to which a linguistic analysis accurately describes the linguistic knowledge or patterns of a speaker or language.

40. Explanatory adequacy

In generative theory, the extent to which an account explains how linguistic knowledge can be acquired, rather than merely describing a language's grammar.

41. Theoretical construct

An abstract concept proposed to explain or organise observations, such as working memory, grammatical competence, or interlanguage.

42. Operationalisation

The process of specifying how an abstract concept will be identified or measured in a particular study.

Example: If a researcher studies speaking fluency, they might operationalise it through speech rate, pause frequency, and pause duration. These measures do not capture every aspect of fluency.

4. Core branches of linguistic analysis

43. Phonetics: The scientific study of speech sounds, including how they are produced, transmitted, and perceived.

44. Phonology: The study of how a language organises sounds into meaningful contrastive systems and patterns.

45. Morphology: The study of word structure and the organisation of morphemes.

46. Syntax: The study of how words and phrases combine to form grammatical expressions and sentences.

47. Semantics: The study of conventional linguistic meaning, including word meaning, sentence meaning, reference, and logical relations.

48. Pragmatics: The study of how utterance interpretation depends on context, communicative intentions, shared knowledge, and inference.

49. Lexicology: The study of the vocabulary of a language, including word relationships, lexical organisation, and meaning.

50. Lexicography: The theory and practice of compiling dictionaries.

51. Discourse: Language used beyond the level of an isolated sentence, interpreted in relation to context, purpose, participants, and surrounding expressions.

52. Grammar: The system of linguistic patterns and constraints governing word formation, sentence structure, and, in broader descriptions, other aspects of language organisation.

53. Linguistic competence: In a classic Chomskyan distinction, a speaker's underlying knowledge of a language.

54. Linguistic performance: The actual use of language in speaking, signing, writing, or comprehension, which may be affected by memory, attention, fatigue, and context.

55. Communicative competence: The knowledge and abilities required to communicate appropriately and effectively in social situations. Dell Hymes introduced the concept partly in response to narrower accounts of grammatical competence.

56. Linguistic acceptability: The extent to which a linguistic expression seems usable or natural to speakers in a given context. Acceptability judgments do not always directly reveal grammaticality because processing difficulty and context can influence them.

57. Grammaticality: Whether an expression conforms to the grammatical system under investigation, as distinguished from whether it is socially appropriate or stylistically preferred.

58. Register: A variety or pattern of language associated with a particular activity, purpose, or situation, such as academic writing, casual conversation, or legal communication.

59. Genre: A socially recognisable type of communicative event with conventional purposes and organisational patterns, such as a research article, job application, lecture, or news report.

60. Style: The linguistic choices a speaker or writer makes, often influenced by audience, purpose, identity, medium, and formality.

Part III. Sociolinguistics and language in society

5. Language variation, identity, and social structure

61. Sociolinguistics

The study of relationships between language and social life, including variation, identity, social class, gender, ethnicity, multilingualism, and language change.

62. Speech community

63. Speech repertoire

The linguistic resources available to a person or community for different social situations.

64. Speech variety

A form of language associated with a particular social, geographical, functional, or historical context.

65. Dialect

A systematic variety of a language that may differ in pronunciation, vocabulary, and grammar. Every speaker uses a dialect, including speakers of prestigious standard varieties.

66. Accent

A pattern of pronunciation associated with a speaker's linguistic, geographical, or social background.

Example: Two speakers may use different English accents while sharing essentially the same grammatical variety.

67. Sociolect

A language variety associated with a social group or social conditions.

68. Idiolect

The distinctive linguistic patterns of an individual speaker.

69. Ethnolect

A variety associated with an ethnic community, often shaped by language contact, identity, and community history.

70. Regional dialect

A variety associated with a geographical area.

71. Standard language

A variety selected, codified, and promoted for particular public or institutional functions, often in education, administration, and publishing.

72. Standard language ideology

The belief that a standard variety is intrinsically more correct, logical, or sophisticated than other varieties, rather than being socially selected and institutionalised.

73. Prestige

The social value assigned to a linguistic variety or feature. Prestige may be overtly recognised by institutions or covertly valued within particular communities.

74. Overt prestige

Social approval associated with varieties regarded as prestigious in mainstream or institutional settings.

75. Covert prestige

The value attached to linguistic forms that signal solidarity, authenticity, local identity, or group membership, even if they lack institutional prestige.

76. Social stratification

The organisation of society into unequal social positions, which may correlate with linguistic differences in particular communities.

77. Sociolinguistic variable

A linguistic feature that has two or more variants whose distribution can be investigated in relation to social or linguistic factors.

Example: Researchers may examine how the pronunciation of a consonant varies with formality, age, or social network.

78. Variable rule

A model of language variation that represents the probability of choosing one variant over another under specified linguistic and social conditions.

79. Style-shifting

Changing linguistic features according to audience, situation, identity, or communicative purpose.

80. Accommodation theory

An approach associated with Howard Giles that examines how speakers adjust their language towards or away from other speakers.

81. Convergence

Adjusting one's language or communicative behaviour to become more similar to another speaker.

82. Divergence

Emphasising linguistic differences from another speaker or group.

83. Audience design

The idea that speakers shape their linguistic choices in response to their audience, including the people they are addressing or orienting towards.

84. Linguistic insecurity

Concern that one's language use is incorrect, inferior, or socially disapproved, often in relation to a prestigious variety.

85. Language attitudes

Evaluations and beliefs about languages, accents, dialects, or speakers.

86. Language and identity

The relationship between linguistic practices and the ways people express, negotiate, or are assigned social identities.

Example: A Pakistani university student may use English in a presentation, Urdu in informal discussion, and Saraiki with family, with each choice reflecting context, relationships, or identity.

6. Multilingualism and language contact

87. Bilingualism

The ability or practice of using two languages. Definitions differ regarding proficiency, frequency, and context of use.

88. Multilingualism

The use or presence of more than two languages at the individual, community, institutional, or societal level.

89. Plurilingualism

An approach, particularly prominent in European language education, that treats an individual's linguistic resources as an interconnected repertoire rather than as entirely separate, self-contained language systems.

90. Code-switching

Alternating between languages or varieties within a conversation or communicative event.

Example: “Assignment kal submit karni hai; please finish the introduction today.”

91. Code-mixing

A term often used for the insertion or combination of linguistic elements from different languages within an utterance. Its distinction from code-switching depends on the analytical framework.

92. Borrowing

The incorporation of linguistic material from one language into another, often with some adaptation to the receiving language.

Example: English bungalow entered English through South Asian language contact.

93. Calque

A loan translation in which the component parts of an expression are translated into another language.

94. Diglossia

A sociolinguistic arrangement in which two varieties have differentiated functions, often involving a high variety for formal domains and a low variety for everyday interaction. The concept is associated with Charles Ferguson and later expanded by Joshua Fishman.

95. Domain of language use

A social setting or activity in which particular language choices tend to occur, such as home, education, administration, religion, or employment.

96. Language shift

A process through which a community increasingly uses another language instead of its traditional language across generations or social domains.

97. Language maintenance

The continued use and transmission of a language despite pressures encouraging a shift to another language.

98. Language revitalisation

Efforts to strengthen a language's transmission, public use, learning opportunities, and community vitality.

99. Language death

The loss of a language when its last fluent speakers die without the language continuing as a living community language.

100. Language endangerment

A situation in which a language faces an elevated risk of losing speakers, intergenerational transmission, or functional domains.

101. Language contact

The interaction of speakers and linguistic systems, which may produce borrowing, convergence, structural change, multilingual practices, or new varieties.

102. Pidgin

A contact language that develops for communication among groups without a shared language, typically with initially restricted functions. Some pidgins later expand in use.

103. Creole

A language that developed historically in a contact setting and became a primary language for a community. Creoles are full linguistic systems, not defective forms of other languages.

104. Translanguaging

An approach to multilingual communication and education that examines how speakers draw flexibly on their linguistic resources to make meaning. In some theoretical accounts, it also challenges the assumption that named languages operate as completely separate systems.

105. Linguistic imperialism

A critical concept, associated especially with Robert Phillipson, concerning how the dominance of a language can reproduce political, economic, or cultural inequalities.

106. World Englishes

A field studying the diversity of English varieties around the world, including their histories, structures, identities, and communicative functions.

107. English as a lingua franca (ELF)

The use of English as a shared means of communication among people who have different first languages.

The capacity of an ethnolinguistic group to maintain its language and collective presence, influenced by factors such as status, institutional support, and demographic strength.

7. Language policy and planning

111. Status planning: Efforts to determine or change the public functions and institutional standing of a language.

112. Corpus planning: Efforts to develop a language's vocabulary, spelling conventions, grammar descriptions, terminology, or writing system.

113. Acquisition planning: Measures intended to influence who learns a language, how it is taught, and how it is transmitted.

114. Prestige planning: Efforts to influence the social image and perceived legitimacy of a language or variety.

115. Official language: A language given formal legal or administrative recognition under a jurisdiction's rules.

116. National language: A language symbolically or politically associated with national identity. Its legal status differs across countries.

117. Medium of instruction (MOI): The language used to teach academic subjects.

118. Mother-tongue education: Education that uses a learner's first or home language, although the exact meaning varies across policy contexts.

119. Linguistic human rights: Rights relating to language use, access to education, and protection against language-based exclusion, as discussed in linguistic and human-rights scholarship.

120. Top-down language planning: Policy initiatives directed by governments, institutions, or other central authorities.

121. Bottom-up language planning: Community-driven efforts to maintain, develop, or promote a language.

Applied example: A university introducing bilingual instruction must consider subject terminology, teacher preparation, student proficiency, assessment practices, access to materials, and the social status of the languages involved.

Part IV. Phonetics and phonology

8. The production and perception of speech

122. Phonetics

The scientific study of speech sounds and their physical properties.

123. Articulatory phonetics

The study of how speech sounds are produced using the vocal tract.

124. Acoustic phonetics

The study of the physical properties of speech signals, including frequency, intensity, duration, and spectral structure.

125. Auditory phonetics

The study of how speech sounds are received and processed through the auditory system.

126. Vocal tract

A structure involved in producing speech sounds, such as the tongue, lips, teeth, alveolar ridge, hard palate, soft palate, or vocal folds.

128. Place of articulation

The location in the vocal tract where a constriction is made to produce a consonant.

Examples include bilabial /p/, dental /θ/, alveolar /t/, velar /k/, and glottal /h/.

129. Manner of articulation

The way airflow is obstructed or modified during consonant production.

Examples include stops, fricatives, nasals, approximants, and affricates.

130. Voicing

A distinction involving vocal-fold vibration during sound production. English /s/ and /z/ contrast in voicing, although voicing details depend on phonetic context.

131. Vowel

A speech sound typically produced without the major oral constriction characteristic of consonants, described in terms of tongue height, backness, and lip rounding, among other properties.

132. Consonant

A speech sound produced with a substantial constriction or closure somewhere in the vocal tract.

133. Diphthong

A vowel sound involving a movement from one vowel quality towards another within a single syllabic nucleus.

134. Syllable

A phonological unit typically organised around a nucleus, often a vowel, with optional onset and coda.

135. Stress

The relative prominence of a syllable, commonly associated with acoustic cues such as duration, intensity, and pitch.

136. Intonation

141. Narrow transcription

A detailed phonetic transcription that includes finer distinctions, often using IPA diacritics.

9. Phonological organisation and processes

142. Phonology

The study of how sounds function as part of a language's system, including contrasts, distributions, and sound patterns.

143. Phoneme

A contrastive sound category capable of distinguishing words or morphemes in a language.

Example: English /p/ and /b/ distinguish pat from bat.

144. Allophone

A contextually or otherwise conditioned phonetic realisation of a phoneme that does not create a lexical contrast in the relevant environment.

Example: English /p/ is commonly aspirated at the beginning of a stressed syllable, as in pin, but usually less aspirated after /s/, as in spin.

145. Minimal pair

Two words that differ in one phoneme in the same position and have different meanings.

146. Complementary distribution

A distribution in which two forms occur in mutually exclusive environments, often supporting an allophonic analysis when other evidence is consistent.

A resonance frequency of the vocal tract visible as a concentration of acoustic energy in a speech spectrum. F1 and F2 are especially useful in vowel analysis.

170. Speech-language pathology

A clinical discipline concerned with the assessment and treatment of communication and swallowing difficulties. Phonetic and phonological analysis can contribute to relevant clinical work.

Part V. Morphology, syntax, and grammatical analysis

10. Word formation and morphology

171. Morphology

The study of the internal structure of words and the ways morphemes combine.

172. Morpheme

The smallest linguistic unit conventionally analysed as carrying meaning or grammatical function.

Example: Unhappiness can be analysed as un- + happy + -ness.

173. Free morpheme

A morpheme that can occur independently as a word, such as book or happy.

174. Bound morpheme

A morpheme that must attach to another element, such as un- or plural -s.

175. Root

The central lexical element of a word, to which other morphological material may attach.

176. Stem

The form to which an inflectional affix is attached. In some analyses, stem has a broader use in derivation and inflection.

177. Affix

A bound morpheme attached to a base, including prefixes, suffixes, infixes, and circumfixes.

178. Prefix

An affix placed before a base, such as un- in unhappy.

179. Suffix

An affix placed after a base, such as -ness in kindness.

180. Infix

An affix inserted within a base. Infixation is productive in some languages and limited or expressive in others.

181. Circumfix

A discontinuous affix with elements placed around a base.

182. Inflection

Morphological marking that expresses grammatical information such as tense, number, person, or case, without normally creating a new lexeme.

Example: Walk and walked are forms of the same lexeme.

183. Derivation

Word formation that creates a new lexeme or changes a word's grammatical category or meaning.

Example: Happy becomes happiness.

184. Compounding

The formation of a word from two or more bases, as in blackboard or toothbrush.

185. Reduplication

The repetition of all or part of a linguistic form to express a grammatical, semantic, or discourse function.

186. Suppletion

The use of historically distinct forms within the paradigm of a single lexeme, as in go and went.

187. Allomorph

One of the alternative forms of a morpheme.

Example: English plural endings have different pronunciations in cats, dogs, and buses.

188. Morphological productivity

The extent to which a morphological pattern can be used to form new words or word forms.

189. Paradigm

A set of related forms associated with a lexeme or grammatical category.

190. Lexeme

An abstract vocabulary unit representing a family of inflected forms. Go, goes, went, and gone belong to the same lexeme in English.

191. Grammaticalisation

A process through which a lexical item or construction develops a more grammatical function, often over time.

192. Clitic

A grammatical element that behaves partly like a word but depends phonologically on a host.

193. Morphological typology

The comparison of languages according to the ways they structure words, including patterns often described as isolating, agglutinative, fusional, or polysynthetic.

194. Agglutination

A morphological pattern in which distinct grammatical meanings are often expressed by separable affixes, each associated relatively consistently with a function.

195. Fusional morphology

A pattern in which a single morphological form may express several grammatical features that are not easily separated into distinct affixes.

196. Isolating morphology

A pattern characterised by relatively little inflectional morphology, with grammatical relationships often expressed through word order, particles, or separate words.

These labels describe tendencies rather than mutually exclusive categories. A single language may display several morphological patterns.

11. Syntax and sentence structure

197. Syntax

The study of how words and phrases combine into larger grammatical structures.

198. Constituent

A word or group of words that functions as a structural unit in a sentence.

Example: In The student read the book, the student is a noun phrase constituent.

199. Phrase

A syntactic unit organised around a head, such as a noun phrase, verb phrase, or prepositional phrase.

200. Head

The central element of a phrase that determines important grammatical properties of the phrase.

201. Complement

A constituent selected or licensed by a head to complete its syntactic or semantic requirements.

Example: In rely on evidence, the prepositional phrase on evidence is selected by the verb rely.

202. Adjunct

An optional modifier that adds information without being selected in the same way as a complement.

Example: Yesterday in Sara read the book yesterday is an adjunct.

203. Argument

A participant or expression required or licensed by a predicate's lexical or structural properties.

204. Predicate

An expression that attributes a property or relation to one or more arguments.

205. Subject

A grammatical relation commonly associated with agreement, clause structure, and particular syntactic positions. Its properties vary across languages.

206. Object

A grammatical relation often associated with a participant affected by an action or otherwise selected by a predicate. Direct and indirect objects can be distinguished in many languages.

207. Direct object

An object that typically bears the most direct object relation to a transitive verb.

Example: The student read the book. The phrase the book is the direct object.

208. Indirect object

Part XIX. Important concepts in language acquisition, teaching, and classroom research

36. Classroom interaction and feedback

931. Initiation-Response-Feedback (IRF)

A common classroom interaction pattern in which the teacher initiates an exchange, a student responds, and the teacher provides feedback or evaluation. The pattern can support instruction but may restrict student-led dialogue if used exclusively.

932. Initiation-Response-Evaluation (IRE)

A closely related interaction pattern in which the teacher initiates, a student responds, and the teacher evaluates the answer.

933. Display question

A question for which the teacher already knows the answer and seeks to check knowledge or elicit a particular form.

934. Referential question

A question to which the speaker does not already know the answer, often inviting more open communication.

935. Wait time

The pause a teacher allows after asking a question or receiving an answer before speaking again or inviting another response.

936. Uptake

A learner's response to feedback or instruction, such as a correction, repetition, clarification request, or modified answer.

937. Repair initiation

A conversational move that signals a problem in hearing, understanding, or producing an utterance and prompts clarification or correction.

938. Repetition in classroom discourse

The reuse of a linguistic expression to confirm, reinforce, clarify, or draw attention to content.

939. Revoicing

A teaching practice in which an educator restates a student's contribution to clarify its meaning, connect it to other ideas, or make it available for further discussion.

940. Dialogic teaching

An approach that uses structured dialogue to support reasoning, explanation, exploration, and the development of understanding.

941. Exploratory talk

A form of collaborative discussion in which participants explain ideas, give reasons, consider alternatives, and critically engage with one another's contributions.

942. Corrective recast

A recast specifically intended to reformulate a learner's non-target-like language in a more appropriate form.

943. Explicit corrective feedback

Feedback that directly identifies an error or supplies information about the target form.

944. Implicit corrective feedback

Feedback that signals a problem or reformulates language without explicitly stating that an error has occurred.

945. Feedback timing

The point at which feedback is provided, such as immediately during a task or after a task has been completed.

946. Feedback uptake rate

The proportion of relevant feedback episodes followed by a specified learner response, as defined by the study's coding scheme.

947. Classroom interactional competence

The ability to use interactional resources effectively for teaching and learning, including turn-taking, questioning, explanation, and repair.

948. Teacher talk

The language teachers use to explain content, give instructions, manage activities, question learners, and provide feedback.

949. Student talk time

The amount or proportion of classroom time during which students speak. Its value depends on the purpose and quality of participation, not simply the quantity.

950. Learner engagement

The cognitive, behavioural, emotional, and social involvement of learners in learning activities.

Part XX. Additional advanced concepts for contemporary applied linguistics

37. Language, cognition, and social practice

951. Embodied cognition

952. Conceptual metaphor theory

An approach associated with George Lakoff and Mark Johnson that examines systematic mappings between conceptual domains and their expression in language.

953. Frame semantics

An approach associated with Charles Fillmore in which word meanings are interpreted in relation to structured background knowledge and recurring situations.

954. Constructional meaning

Meaning associated with a conventional grammatical or lexical pattern, not necessarily reducible to the meanings of individual words alone.

955. Emergentism

A family of approaches in which linguistic structure is understood as emerging from interacting cognitive, social, developmental, and usage-based processes.

956. Complex adaptive systems approach

An approach that studies language as a dynamic system arising from interactions among speakers, cognitive processes, linguistic forms, and social environments.

957. Dynamic systems theory in SLA

An approach that examines language development as a changing, nonlinear process in which multiple interacting factors influence development over time.

958. Language processing and prediction

The investigation of how prior linguistic and contextual knowledge influences expectations about upcoming language.

959. Statistical regularity

A recurring distributional pattern that can be measured in linguistic data, such as the frequency of a word sequence or a grammatical construction.

960. Linguistic entrenchment

The strengthening of a linguistic representation or pattern through repeated use and experience.

961. Grammaticalisation pathway

A commonly observed route through which a linguistic expression develops new grammatical functions over time. Such pathways are tendencies, not universal rules.

962. Language variation and change

The study of how linguistic forms vary across speakers, settings, and time, and how particular variants become established or disappear.

963. Apparent-time study

A method for investigating language change by comparing age groups at one period, under the assumption that some age-related differences reflect historical change.

964. Real-time study

A study that compares linguistic evidence collected at different periods to investigate actual change over time.

965. Linguistic diffusion

The spread of linguistic features across speakers, communities, or geographical areas.

966. Grammaticalisation and language contact

The investigation of how contact between languages may influence the development of grammatical patterns, alongside internal developments and other historical factors.

967. Epistemic stance

The expression of a speaker's degree of certainty, commitment, or knowledge concerning a proposition.

968. Evidentiality

A grammatical or lexical system indicating the source or type of evidence for a proposition, such as direct observation, inference, or reported information.

969. Modality

The expression of possibilities, necessities, obligations, permissions, abilities, or related notions.

970. Egophoricity

A grammatical phenomenon associated in some languages with privileged access to knowledge, experience, or awareness, often depending on person and discourse context. Its exact properties vary across languages.

38. Academic and disciplinary applications

971. English for Research Publication Purposes (ERPP)

Instruction and research focused on the language and rhetorical practices needed to publish scholarly work in English.

972. Academic discourse community

A group of researchers, teachers, or students who share conventions for producing, evaluating, and interpreting disciplinary communication.

A functional section of a text that contributes to its communicative purpose.

975. Move analysis

The identification and analysis of rhetorical moves in genres to understand how writers organise texts for particular purposes.

976. Metadiscourse in academic writing

Final academic note: This is an extensive teaching glossary of 990 numbered entries, not a literally exhaustive dictionary of the discipline. Applied linguistics continues to evolve, and terms sometimes have different definitions across theoretical traditions. For lectures, examinations, and research, students should distinguish established definitions from disputed hypotheses, identify the framework in which a technical term is being used, and support advanced claims with primary research or authoritative scholarly references.
