Collective nouns name groups composed of members, things, or animals.
Each collective noun above works as one unit, even though it is made up of more than one person or thing. You can’t have a committee, team, or family of one; you need at least two of something to compose the unit, but it still acts as one. Consequently, all these collective nouns are singular and require a singular verb and pronoun. (Note: Singular action verbs often end with the letter ‘s’ but should not be confused for the ‘s’ that makes a noun plural.)
