Attaching Prefixes and Suffixes: Bits and Pieces
Prefixes are word parts you add to the beginning of a word to change its meaning; suffixes are word parts you add to the end of a word to change its meaning. Because many useful words are created by adding prefixes and suffixes to root words, you can save a lot of time wondering “Did I spell this sucker correctly?” by knowing how to add prefixes and suffixes. Let's take a look at the guidelines.
Attaching Prefixes: Front-End Collision
The rule here is simple: Don't add or omit a letter when you attach a prefix. Keep all the letters—every one of them. Here are some examples.
You Could Look It Up
Prefixes are word parts you add to the beginning of a word to change its meaning; suffixes are word parts you add to the end of a word to change its meaning.
Attaching Suffixes: Rear-End Collision
Keep all the letters when you add a suffix … unless the word ends in a y or a silent e. We'll talk about them later. The following chart and guidelines show you how to master the suffix situation.
- If the letter before the final y is a consonant, change the y to i and add the suffix. Study these examples.
- Hurry doesn't follow the rule: hurry + ing = hurrying. Here are some other exceptions: dryly, dryness, shyly, shyness, babyish, ladylike.
- If the letter before the final y is a vowel, do not change the y before attaching a suffix.
- Here are some exceptions: laid, paid, said, mislaid, underpaid, unsaid.
- If the suffix begins with a vowel, drop the silent e. Here are some examples.
- When the word ends in ce or ge, keep the e if the suffix begins with a or o: noticeable, manageable, advantageous. Here are some common exceptions: acreage, mileage, singeing, canoeing, hoeing.
- If the suffix begins with a consonant, keep the silent e. Here are some examples.
- Of course there are some exceptions: argument, duly, truly, wholly, and ninth.
- If the word ends in ie, drop the e and change the i to y. Check out these examples.
- Add ly to change an adjective to an adverb. Here are some examples.
- If the adjective ends in ic, add al before ly.
- If the adjective ends in ble, change ble to bly.
- In a one-syllable word, double the final consonant before a suffix beginning with a vowel.
- Don't double the final consonant if it comes after two vowels or another consonant. For example: failed, stooped, warmer, lasting.
- In a word of two or more syllables, double the final consonant only if it is in an accented syllable before a suffix beginning with a vowel. Here are some examples:
- Don't double the final consonant if it comes after two vowels or another consonant. For example: obtained, concealed, abducting, commendable.
- If a words ends in ic, insert a k after the c.
- There's only one hint for adding able or ible: an adjective usually ends in -able if you can trace it back to a noun ending in -ation. Sensible is the exception.
- But there are many words that don't fit this rule, so this isn't the rule to have tattooed on your palm.
