Collective noun

In linguistics, a collective noun is a word which refers to a collection of things taken as a whole. Most collective nouns in everyday speech are mundane and are not specific to one specific kind, such as the word "group," which may apply to "people" in the phrase "a group of people" but may also correctly refer to "dogs," in the phrase "a group of dogs." Other collective nouns are specific to one kind, especially terms of venery, which are words for specific groups of animals. For example, "pride" as a term of venery always refers to lions, never to dogs or cows.
