Rules for Spelling Correction

 

Spelling Correction Rules

Rule 1:  When the suffix “full” is added to a word, one “ I” is removed.
Eg-

• 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.
Eg:

• 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 ‘I’ is doubled in the words ending in single vowel + “I” before a suffix beginning with a vowel eg.

• Signal + ing = signalling
• Repel + ent = repellent
• Quarrel + ed = quarrelled
• Travel + er = traveller

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

• Hope + ing = hoping
• Live + ed = lived
• Drive + er = driver
• Tire + ing= tiring

Rule 6: If the suffix begins with a consonant “e” is not dropped e.g

• Hope + full = hopeful
• Sincere + ly= sincerely

But,

• True + ly = truly
• Nine + th = ninth
• Argue + ment = argument

Rule 7:  A final “y” following a consonant changes to “i” before a suffix except “ing”. Eg.

• Carry + ed = carried
• Happy + ly = happily
• Marry + age = marriage
• Beauty + full = beautiful

But,

• Marry + ing = marrying
• Carry + ing = carrying

Rule 8:  A final “y” following a vowel does not change before a suffix. Eg:

• Obey + ed = obeyed
• Play + er = player
• Pray + ed= prayed

Rule 9: When the suffix “out” is added to a word ending in “ce”, “e” is changed to “i”.
Eg:  

• Space + ous= spacious
• Vice + ous= vicious
• Malice + ous = malicious
• Grace + ous= gracious

Rule 10: When the suffix “ing” is added to a word ending in “ie”, “ie” is changed to “y”.
Eg;

• Lie + ing= lying
• Die + ing = dying
• Tie + ing= tying
