A collective noun is a type of noun that refers to a group or collection of people, animals, things, or entities as a single unit or entity.
Unlike regular countable nouns that refer to individual items, collective nouns emphasize the group as a whole. Examples include “team,” “herd,” “committee,” “family,” and “flock.”
Collective nouns can take either singular or plural verbs and pronouns, depending on whether the emphasis is on the group acting as one entity or as individuals within the group.
They are important in English for describing and categorizing various collective groups efficiently.
