manciple (n.)

"officer or servant who purchases provisions for a college, monastery, etc.," c. 1200, from Old French manciple "steward, purveyor," from Medieval Latin mancipium "office or function of a manceps," from manceps (genitive mancipis) "a purchaser, contractor," etymologically "a taking in hand," from manus "hand" (from PIE root *man- (2) "hand") + stem of capere "to take" (from PIE root *kap- "to grasp"). In classical Latin, mancipium was "a servant, slave, slave obtained by legal transfer" (compare emancipate); also "a formal purchase, the legal purchase of a thing."
