Vowel suffixes are simply suffixes that begin with a vowel, such as -ed, -es, -ing, -er, -y, -en, -est, or -able. Remember, a suffix is always added to the end of a base word.
Here's a helpful strategy designed to help students spell CVC and silent e base words that change when adding a vowel suffix.
If the word has a vowel suffix, use the following rules:
- If the base word ends in a CVC pattern, double the final consonant in the base word before adding the suffix (the doubling rule). For example, when the vowel suffix -er is added to the word big, the final g is doubled and the word becomes bigger (big + er = bigger).
- If the base word ends in a silent e, drop the e before adding the suffix (the silent e rule). For example, when the vowel suffix -ing is added to the word make, the silent e is dropped and the word becomes making (make + ing = making).
If a double consonant precedes a vowel suffix, the vowel in the base word is short. If a single consonant precedes a vowel suffix, the vowel in the base word is long.
Teaching students about vowel suffixes will help students to read larger, more complex words and discover their meaning.
