Answer 2

Nouns can take several forms. Two of those forms are singular and plural. A singular noun names only one person, place, thing, or idea. A noun that names two or more people, places, things, or ideas is a plural noun. How do you make a singular noun plural? Most of the time making a singular noun plural is as simple as adding an s to the end of the word.

Singular Plural

bird birds

book books

cat cats

dog dogs

pen pens

However, some nouns don't follow this rule, and they're known as irregular nouns. How do I change a singular irregular noun to plural? The next sections will help you answer this question.

Irregular Nouns Plural

First, we will look at singular nouns ending with s, ss, ch, sh, x, or z. If a singular noun ends with s, ss, ch, sh, x, or z, add es to the end of the noun.

Let's look at some examples:

walrus - walruses

moss - mosses

beach - beaches

bush - bushes

fox - foxes

ditch - ditches

How do I make a noun plural if it ends with an o? I'm glad you asked!

If the singular noun ends with a vowel, the letters a, e, i, o, and u, most of the time you just add an s.

Some examples include:

kangaroo - kangaroos

rodeo - rodeos

video - videos

Many times, if a singular noun ends with a consonant + o, add an es at the end. Consonants are all the letters of the alphabet except a, e, i, o, and u.

Here are a few examples:

domino - dominoes

echo - echoes

potato - potatoes
