11. Circle, club, coterie, set, society are terms applied to restricted social groups. A circle may be a little group; in the plural it often suggests a whole section of society interested in one mode of life, occupation, etc.: a sewing circle; a language circle; in theatrical circles. Club implies an association with definite requirements for membership and fixed dues: an athletic club. Coterie suggests a little group closely and intimately associated because of congeniality: a literary coterie. Set refers to a number of persons of similar background, interests, etc., somewhat like a clique ( see ring1 ) but without disapproving connotations; however, it often implies wealth or interest in social activities: the country club set. A society is a group associated to further common interests of a cultural or practical kind: a Humane Society.
