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?

Hello Sir,
If the verb "are" skip in the sentence then we could make as " The most interesting country I have visited in Asia."

Hello Imran 26,

I'm afraid that 'The most interesting country I have visited in Asia' is not a complete sentence, as the subject of the sentence ('the most interesting country [that] I have visited in Asia' has no verb ('[that] I have visited' is a relative clause, which here qualifies the subject 'country'), which is required in a complete sentence. You could use that phrase as a title of an article, for example, and that would be fine – but it's not a complete sentence.

Hello Sir,
I have select "Country" in the last sentence but result shows that "Countries " is correct.
could you tell me the reason why should we write Countries. "The most interesting " in the beginning of that sentence that its in important among once, so there will be use singular noun. Kindly let me know the correct sense.

Hello Imran,

In that sentence, only 'Countries' is correct – notice the verb 'are' later in the sentence. 'are' is a verb that takes a plural subject – this is why the answer must be 'Countries'. As you can see, the superlative can be used to talk about more than object when you're talking about a group of objects, such as in this sentence.

Sir,
at above Class is a collective noun and already represent more the one pupil. so why do use use es to make this noun plural?

Hello Imran 26,

Like many collective nouns, 'class' can refer to a group as individuals or to the group as a whole. It can also be used to mean 'course', 'lesson'.

 

Best wishes,

I found the exercise very tricky and love to solve it. I've learnt a lot from this exercise, will do it again until i learn it deeply.
I have studied many English grammar books but in these exercises (available on this site) is quite different and result oriented.
