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 |

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 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 |
