Frater vs. Friar — What's the Difference?

A monk.

A friar is a brother and a member of one of the mendicant orders founded in the twelfth or thirteenth century; the term distinguishes the mendicants' itinerant apostolic character, exercised broadly under the jurisdiction of a superior general, from the older monastic orders' allegiance to a single monastery formalized by their vow of stability. The most significant orders of friars are the Dominicans, Franciscans, Augustinians and Carmelites.
