"steward," O.E. gerefa, of unknown origin and with no known cognates. Not connected to Ger. Graf (see margrave). An Anglo-Saxon official of high rank, having local jurisdiction under a king. Cf. sheriff.
"to wander with no fixed destination," 1536, possibly a Midlands dialectal variant of northern Eng. and Scottish rave "to wander, stray," from M.E. raven, probably from O.N. rafa "to wander, rove." Infl. by rover (q.v.). Earliest sense was "to shoot arrows at a mark selected at pleasure or at random"
