COUNTABLE AND UNCOUNTABLE NOUNS

                             
A noun can be countable and uncountable.

Countable

L like bananas.

Countable nouns (or count nouns) are thigs we can count They have both singular and plural forms (e.g. cat/cats; woman/women; country/countries). In the singular, they can be preceded  by a or an. Most nouns come into this category.

You can use A or AN  with singular countable nouns.

We use MANY and FEW with plural countable noun.

Uncountable

Rice is an uncountable noun.
Uncountable nouns are things we cannot count. 
An uncountable noun has only one form (rice).

We cannot usually use A / AN with uncountable nouns. We do not say "a sand" or "a music". But you can often use A...OF

Example:   a bowl of rice                                a piece of music
