Irregular Plural Nouns

Singular and Plural Nouns

What's the difference?

A noun is a person, place, thing, animal, or idea.
A singular noun names one person, place, thing, animal, or idea.
A plural noun names more than one person, place, thing, animal, or idea.

​What are irregular plural nouns?

An irregular plural noun is a word that becomes plural in a different way than most words, meaning you can't just add an "-s," "-es," or "-ies" to the end to make it more than one.

To make a noun that ends with - f or -fe, drop the -f or -fe and replace it with -ves.
life --> lives
