IPA: /ˈklɪkɪʃnəs/
KK: /ˈklɪkɪʃnəs/
The quality of being exclusive or forming small, tight-knit groups that do not welcome outsiders.
The cliquishness of the group made it hard for new students to make friends.
Cliquishness is formed from "clique" (from French *clique*, meaning a group of people who share a common interest) and "-ish" (meaning having the quality of) and "-ness" (meaning a state or condition). The word describes the state or quality of being cliquish, or forming exclusive groups.
Think of a 'clique' as a group of people who are exclusive, and the '-ish' means having that quality, while '-ness' indicates the state of being. So, cliquishness refers to the state of being part of an exclusive group.
