Explanation

To make a word plural in English, you normally add an -s to the word. For example street becomes streets.

 

But there are also several words that have their own rules, like:

- Words that end with an s, ch, sh, x, or z get an -es (box - boxes).

- If the word ends with a consonant (any letter that is not an a, e, i, o, u) + and has a y too, for example, party, the -y gets replaced with an -ies. So the word party becomes parties in plural.

- If the word ends with an -f or -fe, then it becomes -ves (life - lives).

 

Some words can change to a completely different word in the plural form. Here are a few examples:

- Man - Men

- Woman - Women

- Child - Children

- Person - people

- Foot - feet

- Tooth - teeth

 

A trick that can help you when dealing with irregular verbs in plural form is to remember that many words for animal become irregular in plural form:

- Mouse - mice

- Goose - geese

- Fish - fish

- Deer - deer
