Common errors

1. Uncountable or 'mass' nouns do not go with numbers, and rarely with plural forms or articles.

Uncountable, or 'mass' nouns, define abstract qualities, materials, liquids, collections and things we conceptualise as being without separate identities or boundaries.

2. Some determiners only go with countable nouns (many, few, several, every etc). Others only go with uncountable nouns (much, little, less etc). Use the correct type.

3.Some uncountable nouns are only plural, with no singular equivalent. Common examples include arms (weapons), trousers, glasses (spectacles), goods, groceries, clothes, thanks, police, customs (at national boundaries), remains. They can be used with the definite article 'the', but not with the indefinite article 'a/an' or numbers.

4.Mixed uses 1: Lots of nouns have both countable and uncountable forms (often with the former being composed of the latter). Contrast:

5. Mixed uses 2: Lots of abstract nouns have both countable and uncountable forms when their meaning is more or less particular. Contrast:
