A collective noun is a noun that names a group made up of individual members. In English, it treats the group as a single unit for grammatical purposes. Collective nouns can refer to people, animals, or things. The members of the group are not named individually in the sentence.

English has common collective nouns for groups of people, animals, and objects. These nouns are learned as fixed terms and are used to refer to the whole group. They do not change form based on the number of members in the group. The same word can appear in different categories by convention.

In English, collective nouns often take singular verbs and singular pronouns when the group is acting as a unit. They can take plural verbs and pronouns when the focus is on the individual members acting separately. This choice depends on meaning and context, especially in British and American English.

The choice between singular and plural agreement with collective nouns is guided by whether the sentence treats the group as a whole or emphasizes individual actions. Words in the sentence can signal this focus, such as using "as a group" for unity or mentioning individual members for plurality. Possessives and pronouns also follow the same logic in reference.

Collective nouns name groups as single units in English and commonly take singular agreement when the group acts together. The same noun can take plural reference if the meaning highlights individual members. Correct use depends on understanding the focus of the sentence and the conventions of the dialect.
