Countable nouns can be quantified or counted. Countable nouns have a singular and a plural form. In plural, these nouns can be used with a number- they can be counted hence they are given the term "countable nouns".
Countable nouns:
Few countable nouns only have a plural form in English. Here are a few examples:
These are often used with some sort of quantity word to show how they are counted (e.g., "a pair of" pants, "two pairs of" pants, "some" pants).
Uncountable nouns (non-count nouns):
Examples:
-work, equipment, homework
-air, ice, water, fire
-food: milk, rice, coffee
-abstract concept: advice, happiness, health, education, research, knowledge, information, time
-disease: diabetes, measles, polio, influenza, fever
-activity: swimming, dancing, reading, smoking, playing, bathing
Tip: Nouns that are uncountable do not use the indefinite articles "a" or "an." Nevertheless, they can use the definite article "the" if they are specifically referring to something.
