In linguistics, a collective noun is a word referring to a collection of things taken as a whole. Most collective nouns in everyday speech are not specific to one kind of thing. For example, the collective noun "group" can be applied to people ("a group of people"), or dogs ("a group of dogs"), or objects ("a group of stones").
Some collective nouns are specific to one kind of thing, especially terms of venery, which identify groups of specific animals. For example, "pride" as a term of venery always refers to lions, never to dogs or cows. Other examples come from popular culture such as a group of owls, which is called a "parliament".
Different forms of English handle verb agreement with collective count nouns differently. For example, users of British English generally accept that collective nouns take either singular or plural verb forms depending on context and the metonymic shift that it implies.
Morphological derivation accounts for many collective words
