Spelling with Affixes

Words can be combined with word parts to form new words.

Prefixes: A prefix is a meaningful word part that can be added to the beginning of a base word.

Suffixes: A suffix is a meaningful word part that can be added to the end of a base word. Some common word endings include -ed, -ing, -er, -s, -es,
and -ment.

Rules for Adding Suffixes to Words

⚜ RULE #1: One-Syllable CVC Words

When adding -ed, -ing, or any suffix beginning with a vowel to a one-syllable word with a closed CVC pattern, the final consonant is usually doubled.

⚜ RULE #2: Words Ending with Silent e

When adding -ed, -ing, or any suffix beginning with a vowel to a word ending with a silent e, drop the e before adding the suffix.

⚜ RULE #3: Words Ending with Consonant + y

When adding -ed or -es to a word ending with a consonant + y, change the y to an i before adding the suffix. Do not change the y to an i when adding -ing to a word ending with a consonant + y.
