There are some kinds of noun in English:
Common nouns: dog, man, table
Proper nouns: France, Madrid, Mrs. Smith, Tom
Abstract nouns: beauty, charity, courage, fear, joy
Material nouns: iron, snow, tea
Collective nouns: crowd, group, swarm, team
Class nouns: book, friend.
Collective nounsare subdivided into
1) Nouns used only in the singular (foliage is, machinery is)
2) Nouns which are singular in form but plural in meaning (police, cattle, people, gentry, clergy are)
3) Nouns that can be both singular and plural (crowd – crowds, fleet – fleets)
If a collective noun denotes a thing as a whole it is used with a singular verb. If it denotes a number of people or elements it is used with a plural verb.
e.g. The Russian team was playing well. The hockey team are coming tonight.
My family is small. My family are having tea now.
