Plurals

When a countable noun refers to two or more things you have to use the plural form of the noun.

PLURAL FORMS

Plurals are generally creatid by adding an "s" to make a plural noun:

book > books; school > schools; friend > friends

You need to add -es to nouns ending in –ss; -ch; -s; -sh; -x

class > classes; watch > watches; gas > gases; wish > wishes; box > boxes

When a noun ends in a consonant and -y we make the plural in -ies...

lady > ladies; country > countries; party > parties

…but if a noun ends in a vowel and -y simply add -s:

boy > boys; day > days; play > plays

But there are exceptions: IRREGULAR PLURALS

Irregular nouns do not follow the previous rules. These are the most common:
 
Woman   Women 
Man   Men
Child  Children
Foot  Feet

Tooth  Teeth

And some more irregular plurals..
Sheep Sheep (no change)
Mouse Mice
