motto

n. saying that represents a certain philosophy or code of conduct slogan, catch-phrase; appropriate inscription

A motto (from Italian) is a phrase or a short list of words meant formally to describe the general motivation or intention of an entity, social group, or organization. Many countries, cities, universities, and other institutions have mottos, as do families with coats of arms.A motto may be in any language.  Latin and to a lesser degree French are disproportionately frequent, because each was the principal international language for a considerable period. The local language is usual in the mottos of governments.Fraternities and sororities typically have their (usually secret) mottos in the Greek language. That of the County of Somerset is in Anglo-Saxon.
