In this lesson you will learn the rules when using irregular plurals of nouns. Make sure you read our other article about regular plurals after this one.

Irregular Plural Nouns

The spelling of some nouns are completely changed when forming the plural. Unfortunately there isn’t a rule as such, you simply have to learn them.

Here are some common examples.

1 MAN is – 2 MEN are
1 WOMAN is – 2 WOMEN are
1 CHILD is – 2 CHILDREN are
1 FOOT is – 2 FEET are
1 PERSON is- 2 PEOPLE are
1 TOOTH is – 2 TEETH are
1 MOUSE is – 2 MICE are


Names of professions with the word MEN or WOMEN such as

1 POLICEMAN is – 2 POLICEMEN are
1 POLICEWOMAN is – 2 POLICEWOMAN are
1 POSTMAN is – 2 POSTMEN are
1 POSTWOMAN is- 2 POSTWOMEN are

These plurals never need a S on the end. You should never say Peoples, Teeths or Womens when referring to plurals.

Some irregular plurals have the same form as the singular.

1 SHEEP is – 2 SHEEP are
1 FISH is – 2 FISH are
1 DEER is – 2 DEER are

All this might seem complicated at first, but once you get used to it you will be ok.
