SOME SPELLING RULES

At its best, English spelling can be perplexing, especially for non-native speakers and writers. The following rules and suggestions are offered as aids. You will always be able to find exceptions to these rules, but most writers find them helpful.
i before e, except after c . . . .
achieve, believe, bier, brief, hygiene, grief, thief, friend, grieve, chief, fiend, patience, pierce, priest
ceiling, conceive, deceive, perceive, receipt,
receive, deceit, conceit

neighbor, freight, beige, sleigh, weight, vein, and weigh
. . . and some other exceptions. . . .
either, neither, feint, foreign, forfeit, height, leisure,
weird, seize
A final y changes to i when an ending is added .
supply becomes supplies
worry becomes worried
merry becomes merrier
. . . except when that ending is -ing. . .
crying, studying
. . . And when the y is preceded by a vowel. . . .
obeyed, saying
A silent e is dropped when adding an ending that begins with a vowel . . .
advance + -ing = advancing
surprise + -ing = surprising
. . . but kept when the ending begins with a consonant . . .
advancement, likeness
. . . unless the e is preceded by a vowel. . . .
argue + -ment = argument
true + -ly = truly
Adding a prefix seldom changes the spelling of a word.
misspelled
unnecessary
dissatisfied
disinterested
misinform
We form plurals in English by adding -s or -es.
shoes
porches
boxes
bushes
blitzes
For words ending in a consonant plus -y, change the -y to -i and add -es. For proper nouns, keep the -y.
toys
companies
Kennedys
When adding an ending to a word that ends in a consonant, we double that consonant when the ending begins with a vowel and the last syllable of the word is accented and that syllable ends in a single vowel followed by a single consonant.
Now that’s a mouthful! Let’s look at some examples. . . .
ADMIT + -ed = ADMITTED
When adding an ending to a word that ends in a consonant, we double that consonant when the ending begins with a vowel and the last syllable of the word is accented and that syllable ends in a single vowel followed by a single consonant.
ADMIT is accented on the last syllable and the final consonant is preceded by a vowel, so we double the t before adding, for instance, an -ing or -ed : admitting, admitted.
FLAP + -ed = FLAPPED
When adding an ending to a word that ends in a consonant, we double that consonant when the ending begins with a vowel and the last syllable of the word is accented and that syllable ends in a single vowel followed by a single consonant.
FLAP contains only one syllable, which means that syllable has to be accented. The final consonant is preceded by a vowel, so we double that final consonant: flapped, flapping.
COUNSEL + -ing = COUNSELING
When adding an ending to a word that ends in a consonant, we double that consonant when the ending begins with a vowel and the last syllable of the word is accented and that syllable ends in a single vowel followed by a single consonant.
COUNSEL contains two syllables and the final consonant is preceded by a vowel, but the word is accented on the first syllable, so we don’t double the consonant before adding an ending.
BEGIN + -ing = BEGINNING
When adding an ending to a word that ends in a consonant, we double that consonant when the ending begins with a vowel and the last syllable of the word is accented and that syllable ends in a single vowel followed by a single consonant.
BEGIN contains two syllables and the final consonant is preceded by a vowel, and the word is accented on the last syllable, so we double the consonant before adding an ending: beginner, beginning
DESPAIR + -ed = DESPAIRED
When adding an ending to a word that ends in a consonant, we double that consonant when the ending begins with a vowel and the last syllable of the word is accented and that syllable ends in a single vowel followed by a single consonant.
DESPAIR contains two syllables, and the final syllable is accented, but the final consonant is preceded by two vowels, not a single vowel, so we don’t double that final consonant when we add an ending.
Becoming a better speller is a matter of personal commitment and finding your own method to add this important skill to your writing arsenal. Refer to the Guide to Grammar and Writing for recommendations on working on spelling. Also, take the spelling quizzes on the List of Interactive Quizzes.
