What is an irregular plural noun?

Regular plural nouns are  formed by adding s or es to the end of the word. Examples of these cats, or boxes. Irregular plural nouns are not formed in this way. They are formed in a variety of ways and sometimes with no rule at all.

Sometimes they are formed by changing the vowel in the word such as – man to men, or goose to geese.

Nouns ening in –f or –fe often drop these letters and add –ves. Examples are wolf to wolves, or knife to knives.

Nouns ending in –us usually drop those letters and add an i. Words like this include – cactus to cacti, or octopus to octopi.

Some nouns undergo changes that don’t follow the above rules due to historical linguistic reasons. Words like this include – mouse to mice, and person to people.

There are also irregular nouns that don’t change at all when becoming plural. Examples are – sheep, fish, deer, police, and corn.

Many nouns from Greek and Latin also undergo other different changes when becoming plural.
