Singular and plural nouns – There are two forms of nouns: singular and plural. A singular noun is used to refer to just one person, animal, thing or place. For two or more people, animals, places, or things, a plural noun is used. To make a regular noun plural, we add an –s or – es to the end (camel/camels, map/maps; echo/echoes) of the noun. A plural irregular noun has a different ending (hoof/hooves) or spelt differently from the singular noun (tooth/teeth).
