One of the basic rules in English grammar is knowing how to use singular and plural nouns correctly. This guide will help you understand how to form plurals and use them in sentences.

1. What Are Singular and Plural Nouns?

  • A singular noun refers to only one person, place, thing, or idea.
    Example: cat, book, car, child

  • A plural noun refers to more than one person, place, thing, or idea.
    Example: cats, books, cars, children

2. Rules for Forming Plurals

Most singular nouns can be changed into plural forms by following these simple rules:

A. Regular Plurals

  • Add -s to most nouns.
    Examples: dog → dogs, apple → apples, chair → chairs

  • Add -es to nouns ending in -s, -sh, -ch, -x, or -z.
    Examples: bus → buses, box → boxes, church → churches

B. Plurals of Nouns Ending in -y

  • If a noun ends in a consonant + y, change y to i and add -es.
    Examples: baby → babies, city → cities, country → countries

  • If a noun ends in a vowel + y, just add -s.
    Examples: boy → boys, toy → toys, key → keys

C. Plurals of Nouns Ending in -f or -fe

  • Some nouns ending in -f or -fe change f to v and add -es.
    Examples: knife → knives, leaf → leaves, wolf → wolves

  • Some nouns simply add -s.
    Examples: roof → roofs, belief → beliefs

D. Irregular Plurals

Some nouns do not follow the regular rules. You have to memorize these.
Examples:

  • child → children

  • man → men

  • woman → women

  • tooth → teeth

  • foot → feet

  • mouse → mice

E. Plurals of Nouns That Do Not Change

Some nouns remain the same in both singular and plural forms.
Examples:

  • sheep → sheep

  • deer → deer

  • fish → fish

  • aircraft → aircraft

F. Plural of Compound Nouns

  • For most compound nouns, add -s to the main noun.
    Examples: mother-in-law → mothers-in-law, passer-by → passers-by

  • Some compound nouns simply add -s at the end.
    Example: lookout → lookouts, tablespoon → tablespoons
