What is a group of Entities called?

A group of entities is commonly called a Legion.

Collective nouns for entities are used to refer to a group or collection of individual entities, objects, or things. These nouns indicate that multiple entities are being referred to as a unified whole or functioning as a single unit. Instead of naming each individual component separately, a collective noun allows us to conveniently address the entities as a group. These collective nouns can be applied to various types of entities such as people, animals, plants, and objects. For example, when talking about a group of people, we may use collective nouns like "crowd," "team," "audience," or "crew" to describe them collectively rather than naming every person individually. Similarly, for animals, we may use "herd" for elephants or cattle, "pack" for wolves, or "school" for fish. In the case of plants, "forest," "orchard," or "grove" can be used as collective nouns. For objects, collective nouns like "set," "collection," or "fleet" can be employed, depending on the context. Collective nouns help simplify our language and enhance clarity and efficiency in our communication. Instead of using a long list of individual names or items, collective nouns allow us to refer to a broader group as a single unit, whether it's a crowd at a concert, a herd of wild animals, or a collection of books. They provide an effective way to describe and identify groups while eliminating redundancy and enhancing the comprehension of our statements.
