The 10 Golden Rules in Spelling Correction of English Grammar
Rule 1: When the suffix “full” is added to a word, one “ I” is removed.
Faith + full = faithful
Use + full= useful
Rule 2: If the word to which the suffix “full” is added ends in “ll”, one “I” is removed from the word also.
Skill +full = skilful
Will + full= wilful
Rule 3: Words of two or three syllables ending in single vowel + single consonant double the final consonant if the last syllable is stressed. Eg-
Permit + ed = permitted
Occur + ing =occurring
Control + ed =controlled
Begin + ing = beginning
Rule 4: Consonant ‘L’ is doubled in the words ending in single vowel + “I” before a suffix beginning with a vowel eg.
Signal + ing = signalling

Rule 5: Words ending in silent “e”, drop the “e” before a suffix beginning with a vowel eg.

Hope + full = hopeful
Sincere + ly= sincerely
But,
True + ly = truly
