COLLECTIVE NOUNS are a class of nouns which though singular in number, name a group of people or objects. If the members of the group are a unit, then the noun is singular. For example, company, crowd, or team are SINGULAR nouns. If the members of the group are separate, then the noun is plural. For example, class and group are PLURAL nouns.
My favorite collective nouns are the ANIMAL groups. Collective nouns for some groups of animals are really quaint. Easy ones include a group of ants are called a colony or a group of birds are called a flock. Some are more difficult: foxes (skulk), walrus (pod), quail (bevy), kitten (kindle), hog (drift), wild hog (sounder), bee (swarm), elk (gang), duck (plump).
