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?

sir, as u said that the comfort zone is a word combination .for example: 'the baby need a comfort zone'. In this sentence, instead of 'comfort' can we use 'comfortable'? does it change the meaning?

Hello Lavakusha,

Yes, as I suggested in my last comment, in general 'comfort zone' and 'comfortable zone' have different meanings. Please follow the link in my last comment to the definition and note there is an example sentence to illustrate the meaning. 'comfort zone' has a bit more to do with one's psychological state and 'comfortable' has more to do with one's physical state.

hello sir, is there a word called "comfortable zone(literally says comfort zone)" do exist or it is grammatically wrong.

Hello Lavakusha,

'comfort zone' is a common collocation. 'comfortable zone' is possible, though it would probably be used to mean something different. If you have a specific context in mind, please specify it. In any case, it's not as common a word combination as 'comfort zone' is.

Hello Sir
Could you help me to clarify this? 'residence' is a singular noun countable so the plural
of it is: residences.
Please let me know whether I am right or wrong.
Thank you.

Hello Andrew international,

That's correct, 'residence' is a count noun. It has a regular plural form, 'residences'.

Hi,
Is it correct to use the word 'media' for people or is it just for newspapers etc?
I read 'the media was present / the media writes..'. It seems to be like a person. Should it be 'media persons write...?
Regards

Hi Petals,

Yes, the word 'media' is often used to talk about people. For example, you might read 'The media gathered in great numbers for the press conference'.

 

Best wishes,

Hi All!
I don't understand: A lot of is plural why do we use lorry is singular?
also the sentence: He's the sort of person you can trust.
Thank you for your help!

Hello NGUYEN HONG THU THU,

I don't see a sentence with 'a lot of' and 'lorry' on this page, so I'm afraid I don't know what you mean. What is your question about the second sentence?

I'm sorry not to help you -- I just don't understand your questions. Please ask again and we'll do our best to help you.

All the best,
Kirk
