What are singular and plural nouns?

A singular noun means one person, one animal, one place, or one thing.

• Example: a dog, a book, a city.

A plural noun means more than one person, animal, place, or thing.

• Example: dogs, books, cities.

We use plural nouns to talk about many things.

How do we make most nouns plural?

For most nouns, we add -s at the end. This is the most common rule.

Look at these examples:

• one cat → two cats
• one car → two cars
• one table → two tables
• one friend → two friends

When do we add -es to make nouns plural?

If a noun ends with -s, -ss, -sh, -ch, -x, ou -z, we add -es.

This makes the word easier to say.

Here are some examples:

• one bus → two buses
• one class → two classes
• one dish → two dishes
• one watch → two watches
• one box → two boxes
• one quiz → two quizzes

What about nouns ending in -y?

If a noun ends in -y and has a consonant before it (like b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, z), we change the -y to -i and add -es.

Examples:

• one baby → two babies (consonant ‘b’ before ‘y’)
• one city → two cities (consonant ‘t’ before ‘y’)
• one party → two parties (consonant ‘t’ before ‘y’)

Important: If a noun ends in -y but has a vowel before it (like a, e, i, o, u), we just add -s.

• one day → two days (vowel ‘a’ before ‘y’)
• one boy → two boys (vowel ‘o’ before ‘y’)

Are there any special plural nouns?

Yes, some nouns have different plural forms. They do not follow the -s ou -es rules. These are called irregular plurals.

You need to learn them by heart.

Here are a few common ones for beginners:

• one man → two men
• one woman → two women
• one child → two children
• one foot → two feet
• one tooth → two teeth
• one mouse → two mice
