What effect does a collective noun give?

A collective noun gives the effect of grouping or categorizing individual entities as a single unit. It emphasizes the notion of a unified identity or collective characteristic within the group. By using a collective noun, speakers or writers can effectively represent the collective behavior, attributes, or actions of a group as a whole. It allows for simpler and more cohesive expression by condensing information about multiple individuals into a single concept. For example, instead of saying "a crowd of people gathered," one can use the collective noun "crowd" to convey the idea of a collective mass of individuals without having to elaborate on each person separately.
