uncountable

uncountable (utellelig): a feature of some  nouns. An uncountable noun refers to something which is seen as a mass, rather than an entity. Uncountable nouns do not vary between the singular and the plural. They co-occur with singular verbs, determiners and pronouns. E.g. water, tea, sand, pollution, money, furniture, gold. Since uncountable nouns cannot be referred to as 'one' or 'many' they cannot occur with the indefinite article (a/an, which means 'one') either, and they do not combine with the plural -s.
