What is the Singular Form?

  • a dog

  • a house

Singular, Plural Forms of Nouns

singular meaningWhat is the singular form? Most nouns have singular and plural forms. The singular form of the noun refers to just a single item. For instance, “an apple” refers to just one apple.

The plural form of the noun (apples) refers to more than one apple.

For most nouns, “-s” is added to the end of the sentence to create the plural form. When the word ends in “-y,” the “-y” is dropped and “-ies” is added to the end of the word to create the plural form (see below).

Examples of Singular/Plural Nouns

  • dog/dogs
  • cat/cats
  • house/houses
  • tree/trees
  • apple/apples
  • baby/babies
  • city/cities

Count Nouns vs. Non-count Nouns

singular nouns definition A count noun is a person, place, or thing that can have a singular or plural form. Most nouns have both singular and plural forms. Typically, by adding “s” to a noun, the plural form is made. A count noun can be counted.

  • boy/boys
  • home/homes
  • orange/oranges

A non-count noun is a person, place, or thing that does not have a plural form. In a sense, a non-count noun cannot be counted, and since it cannot be counted exactly, there is no plural form of count nouns.

  • equipment
  • storage
  • courage

Consider the last example, courage. The word courage cannot be made plural into “courages.”

Singular Agreement in Number

It is critical that a singular noun has the appropriate agreement with all of its corresponding parts of speech.

Verb Agreement

Examples with “to write:”

  • I write. (singular)
  • You write. (singular and plural)
  • He/She/it writes. (singular)
  • We write. (plural)
  • They write. (plural)

It is grammatically incorrect to state: I writes.
