Other forms: cliques
A clique is a small closed group that keeps others out. A tight clique, cliques at school, form a clique.
The exclusion is what makes it a clique rather than a group of friends, and the word is always a complaint from outside. It is used constantly about schools, offices and committees. Note cliquey, describing a place full of them; and that the French word comes from a verb meaning to click, from the noise of a claque — a group hired to applaud.
