Count nouns

Count nouns have two forms: singular and plural.

Singular count nouns refer to one person or thing:

a teacher a book a wish an idea

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

teachers books wishes ideas

Singular count nouns

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

the English teacher that book a wish my latest idea
Singular count nouns 1


Singular count nouns 2


Plural count nouns

We usually add –s to make a plural noun:

book > books
school > schools
friend > friends

We add –es to nouns ending in –s, –ch, –sh, –ss, –x and –o:  

class > classes
watch > watches
gas > gases
wish > wishes
box > boxes
potato > potatoes

When a noun ends in a consonant and –y, we make the plural with –ies:

lady > ladies
country > countries
party > parties

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
person > people
foot > feet
Plural count nouns 1


Plural count nouns 2


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

Computers are very expensive.
Do you sell old books?

But they may have a specific determiner:

Those computers are very expensive.
The books in that shop are very expensive. 
Her sisters live there.

or a quantifier:

some new books a few teachers lots of good ideas

or a numeral:

two new books three wishes

Hello Nevı,

Prepositional phrases can have adjectival or adverbial functions.


As adjectives, prepositional phrases answer the question 'Which one?'

the book on the table

the man by the car


As adverbs, prepositional phrases answer the questions 'Where?', 'When?', 'Who with?' or 'How?'

dance in the club

meet on Saturday

go with my friend


In your example, on Monday has an adverbial function.

Got that teacher.But I don't understand one thing.
I want to explain in this example sentence;
"China is collaborated with Argentina on buying Vaccines."

Here, Is "with Argentina" an adverb? or a prepositional object? My book says prepositional object?
İn Your example sentence (go with my friend), you said 'with my friend' acts an adverb

-Could you tell me please How I can seperate prepositional object and prepositional adverb?
Thank you
(I am working English by myself)

Hello again Nevı,

I think you're confusing two separate things here: what the prepositional phrase is comprised of and how it is used in the sentence.


A prepositional phrase contains a preposition (with) and the object of that preposition (my friend). These are the elements which make it up.


The prepositional phrase's function in the sentence is a different thing. This can be adjectival (describing a noun) or adverbial (adding information about an action).

Sir, 2 days back I saw in a sop opera a board on a shop like 'Shop on sell' . I have always understood 'sell' as a verb and 'sale' as its noun , and have never seen usage of 'see' as a noun. I checked in the cambridge dictionary and there I found 1 last meaning of 'sell' as a noun - though most of the explanation and examples for 'sell' in the dictionary is for its meaning as verb only. And they are very unlikely to be wrong in the sop opera , which is one of the most widely seen in India. Sir, how do I understand the difference between two nouns - 'sell' and 'sale' - and how do I decide on their usage. Thank you Regards Dipak R Gandhi

Hello dipakrgandhi,

Perhaps I'm missing something, but I can't think of a context in which 'Shop on sell' would be correct, at least in standard British or American English. If I owned a shop and wanted to sell it, I'd use a sign saying 'Shop for sale'.

It sounds to me as if you already understand the difference between 'sale' and 'sell'.

All the best,

Thank you Sir, But, there is a last entry for 'sell' in the cambridge dictionary which explains 'sell' as a noun also . It also asks us to compare this noun 'sell' with 'sale'. And that is what I wish to know from you - the usage of noun 'sell' and noun 'sale' Thank you Regards

Hello dipakrgandhi,

The usage of the noun 'sell' is shown in the example sentences on the Cambridge Dictionary page. I'd suggest you also look up 'sell' in other dictionaries (here's one, here's another) to see other explanations.

I'd be happy to explain the way 'sell' was used on the sign that you spoke about if it were used correctly, but it is not used correctly. I'm afraid I can't explain why they've used it incorrectly.

All the best,

Hello teacher, i have a question related to number :
What is the plural form of number : one, two, three. Is it ones, twos, threes ?
In these sentences:
There are two number three in the lottery.
There are two numbers three in the lottery.
There are twos three in the in the lottery.
Which one is correct, and which one also acceptable in use ?
Thanks !

Hello Jack,

The plural forms of numbers are regular when the word is used as a noun: ones, twos, threes etc. 

None of your examples are correct, I'm afraid! The correct form is as follows:

There are two number threes in the lottery.
