A noun is the name of something. For example: milk, mango, meat, pen, water, food… Some nouns can be counted, whereas others cannot be counted. So, we have countable and uncountable nouns.
Countable nouns are the names of things or people that can be counted. For countable nouns, we talk of singular if we have one item and plural if we have more items.
A banana → bananas
An orange → oranges All the countable nouns must have the indefinite articles (a, an)
A church → churches when they are used in singular
A man → men
An egg → eggs
A dog → dogs
Uncountable nouns or mass nouns are the names of things, feelings and qualities that cannot be counted. They do not have a plural form.
Milk → milk
Oil → oil
Salt → salt Other nouns include water, food, blood, sugar, soil, information, sand, news, bread,
Fish → fish advice, tea, soap, music, luggage, poetry, rice, Physics, Biology, malaria, flour…
N.B: –All uncountable nouns do not take the indefinite articles.
-They take verbs in singular. Ex: Music entertains us.
