Count nouns have two forms: singular and plural.

Singular count nouns refer to one person or thing:

a book; a teacher; a wish; an idea

Plural count nouns refer to more than one person or thing:

books; teachers; wishes; ideas

Singular count nouns

Singular count nouns cannot be used alone. They must have a determiner:

the book; that English teacher; a wish; my latest idea

Plural forms

We usually add –s to make a plural noun:

book > books; school > schools; friend > friends

We 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 we simply add -s:

boy > boys; day > days; play > plays

Some common nouns have irregular plurals:

Man > men; woman > women; child > children; foot > feet;
person > people

Plural count nouns do not have a determiner when they refer to people or things as a group:

Computers are very expensive.
Do you sell old books?




Hi peter is it that "at" refer to a small place or region while "in" refer to big place or region.?Thank you

Hello leeleeho,

I don't think that's a helpful rule, to be honest. You can use 'in' with very small places ('in the box', 'in the drawer' and 'at' with large ones ('at Lake Baikal', 'at Bondi Beach').

I have a query regarding your exercise of count nouns. "I can hear something in the roof. Have you got ________?". Can we use mouse instead of mice in the given sentence?

Thank you

Hello Arjun1989,

Grammatically, it is possible to say 'a mouse' here. However, as the question is about an infestation of mice rather than having one mouse as a pet it does not make sense.

Hello sir,

What are these just laws and unjust laws.

Hello Shrikant J,

I'm not sure what you are asking here. If you need to find out the meaning of 'just' and 'unjust' then an online dictionary is the best place, as there you'll find definitions and examples. If you are asking what we consider just and unjust then I'm afraid we can't answer: it is not our place to give such opinions!

How to say "woman-friend" in the plural?

Hello Liza,

'woman-friend' isn't really standard English, but I suppose I'd say 'woman-friends' is the plural form. Do you perhaps mean 'girlfriend'? A 'girlfriend' can be a woman - see the Cambridge Dictionary entry for more information on what the word can mean.

All the best,

why you select "children" as a answer of second question ?

Hello anuruddha1107,

The verb 'watch' requires a plural subject such as 'children'. If the subject were 'child', the verb would be 'watches'.
