froward \FROH-werd\, adjective:
not easily managed; contrary
The mule is a froward animal.
c. 1300, Old English fromweard "turned from or away," from from + -weard. The opposite of toward, it was Latin pervertus in early translations of the Psalms, and also meant "about to depart, departing," and "doomed to die."
The "doomed to die" bit intrigues me.
Anyone else got any unusual new words recently?
