Mannerism /(?)/

Man·ner·ism

Mannerism

n.
  1. Adherence to a peculiar style or manner; a characteristic mode of action, bearing, behavior, or treatment of others.
  2. Adherence to a peculiar style or manner carried to excess, especially in literature or art.
    Mannerism is pardonable,and is sometimes even agreeable, when the manner, though vicious, is natural . . . . But a mannerism which does not sit easy on the mannerist, which has been adopted on principle, and which can be sustained only by constant effort, is always offensive.
