- degree
- early 13c., from O.Fr. degre "a degree, step, rank," from V.L. *degradus "a step," from L.L. degredare, from L. de- "down" + gradus "step" (see grade). Most modern senses date from M.E., from notion of a hierarchy of steps. Meaning "a grade of crime" is 1670s; that of "a unit of temperature" is from 1727. The division of the circle into 360 degrees is very ancient and was known in Babylon and Egypt. It is perhaps from the daily motion of the sun through the zodiac in the course of a year.
