Collective nouns name a group of people, animals, or things as a single unit. In British English they often take a plural verb; in American English, usually singular. Understanding them helps you sound natural and avoid agreement errors.
A collective noun names a group as one thing: team, committee, staff, jury, audience, family, board. American English treats that one thing as singular, so it takes a singular verb and the pronoun its (The committee announces its decision tomorrow). British English often treats the same noun as plural (the staff are), which is why you see both patterns in print. Put a number or a word like several in front and the collective noun itself becomes plural (five teams are competing), and a few group words — police, people — always take a plural verb.
