NON-COUNT NOUNS

What is a noncount noun?

Noncount (or uncountable) nouns exist as  abstract quantities that cannot be counted. They have no plural form. Although most English nouns are count nouns, noncount nouns frequently occur in academic writing.

Here are some common categories of noncount nouns. Like all things in English (and language in general), there may be exceptions. 

A mass: work, equipment, homework, money, transportation, clothing, luggage, jewelry, traffic

A natural substance: air, ice, water, fire, wood, blood, hair, gold, silver

Food: milk, rice, coffee, bread, sugar, meat, water

An abstract concept: advice, happiness, health, education, research, knowledge, information, time

Important: Noncount nouns do not use the indefinite articles "a" or "an." They can, however, use the definite article "the" if what is being referred to is specific. They can also use no article if what is being referred to is general (generic) or nonspecific.
