Final -s/-es: Use
Use: A final -s or -es is added to a noun to make the noun plural.
A final -s or -es is added to a simple present verb when the subject is a singular noun (Mary, my father, the machine) or third person singular pronoun (He, she, it).
Noun+-s: Friends are important.
Noun+-es: I like my classes.
Verb+-s: Mary works at the bank.
Verb +-es: John watches birds.
Final -es/-es Spelling
For most words (whether a verb or a noun), simply add a final -s to spell the word correctly.
Final -es is added to words that end in -sh, -ch, -s, -z, and -x
For words that end in -y:
If -y is preceded by a vowel, only -s is added.
If -y is preceded by a consonant, the -y is changed to -i and -es is added.
Basic Subject-Verb Agreement
Verb + -s/-es = third person singular in the simple present tense
Noun + -s/es =plural
My friend lives in Boston.
My friends live in Boston.
Two or more subjects connected by and require a plural verb.
Plural: My brother and sister live in Boston.
My brother, sister, and cousin live in Boston.
Exception: Every and each are always followed immediately by singular nouns.
A gerund requires a singular verb
Watching old movies is fun.
Using Expressions of Quantity
In most expressions, the verb is determined by the noun (or pronoun) that follows of.
Some of+singular noun=singular verb
Some of+plural noun=plural verb
One of, each of, and every one of take singular verbs.
Each of }+plural noun=singular verb.
Every one of
None of= singular in very formal English
None of= plural in informal English and sometimes in writing.
