Spelling: Adding -s and -es
We add -s and -es for two reasons:
1. The word is a noun, and we are making it plural.
table → tables
chair → chairs
2. The word is a verb, and it agrees with the subject (he, she, or it–3rd person singular)
I wait → she waits
they cook → he cooks
Spelling Rules
Rule 1:
If a word ends in /s/, /z/, /ch/, /sh/ or /x/ sound → add -es
Only add -es for the he/she/it form of the verb (third person singular).
watch → watches
wash → washes
kiss → kisses
I pass out papers. → She passes out papers.
I wash the dishes. → He washes the dishes.
Exercise 1.16: Spelling Rule 1
Directions: Write the correct form of the verb in parentheses on the lines.
Add -es if the verb ends in /s/, /z/, /ch/, /sh/ or /x/

Rule 2:
If a word ends in a consonant plus -y, change -y to i and add -es. If the word ends in a vowel plus -y, just add -s.
Consonant + -y Change -y to i and add -es
cry → cries
study → studies
Vowel + -y Add -s
pay → pays
buy → buys
Rule 3:
After the letter o. The spelling depends on the origin of the word. You may need a dictionary!
We add the suffix –es to most words that end in o.

We add the plural suffix –s to words of foreign origin (Latin, Greek, Spanish, etc.)
