What Are Singular Nouns?

Singular nouns are words that refer to one person, one place, one thing, or one idea. They are used when you are talking about a single item only. For example, words like a boy, a school, an apple, and a book are singular nouns because each one refers to just one thing.

Singular nouns are very important in English because they help you form correct sentences and match verbs properly. For example, you say the boy is playing, not the boy are playing. In simple words, whenever you are talking about only one thing, you are using a singular noun.
