Home » Listening » Number: How to Form Plurals of Nouns

The number is a grammatical category. Numbers express the count distinctions of a noun or pronoun.

Example: a girl, ten girls, a boy, boys, etc

Types of Number

There are two types of numbers in grammar:

  1. singular and
  2. plural.

Singular number

  • When a noun expresses a person or thing, it is called singular.

Example: mother, bird, pen, mobile

Plural number

  • When a noun expresses more than one object or person, it is called a plural.

Example: mothers, birds, pens, mobiles

How to change the number

There are some rules for forming a plural number from a singular.

Have a look-

Rule 1

We can make the plural form of a noun simply by adding -s to the singular.

Examples:

  • Cat
      cats
  • Pencil
    pencils
  • Day

  • Desk
    desks

Rule 2

A noun ending in -y that follows a consonant becomes plural by changing -y to -ies.

Examples:

  • City
    cities
  • Country
    countries
  • Fly
    Error occurred when trying to fetch the file using wp_remote_get(). cURL error 35: Recv failure: Connection reset by peer

Rule 3

The plural form of a noun ending in -ch, -sh, -ss, or -x is made by adding -es.
