Plural Nouns

When you are talking about two or more people, animals, places, or things, use plural nouns.

Most nouns are made plural by adding -s at the end.

Some plural nouns end with -es

When the last letters of singular nouns are ch, sh, s, ss, or x, you usually add -es to form the plural.

Some plural nouns end in -ies.

Nouns like these are made plural by changing y to i, and adding -es.

What if there is a vowel before the y?

    In that case, add -s to form the plural.

If a noun ends in -f, you often change f to v, and add -es.

With some words that end in -fe, you change f to v, and add -s.

If a noun ends in -o, you just add -s to form the plural.

But with some nouns that end in -o, you add -es to form the plural.

Some plural nouns don't follow the -s rule. They don't end in -s, -es, -ies or -ves. Instead, the word changes form.
