c. 1300, "legal condition of a serf or slave," from Middle English bond "a serf, tenant farmer," from Old English bonda "householder," from or cognate with Old Norse boandi "free-born farmer," noun use of present participle of boa "dwell, prepare, inhabit," from PIE *bhow-, from root *bheue- "to be, exist, grow." For sense evolution, see bond (adj.). The sexual sado-masochism sense is recorded by 1963 (in a New York law against publications portraying it).
