Assorted Slang and Terminology - Volume 3 - Collective Nouns

A collective noun is a name for a collection or group of things. 

Rather than saying “that group” or “or those (x) over there” you would use a collective-noun to give the group/collection its proper name.

The following format is used for each entry:
[subject] [collective noun]

This would tell you that, for example, the collective noun for a group of apes would be a troop – “We must be careful, there is a large troop of apse that live here and they don’t like visitors”
