Word Origin and History for swarm

n.

"cloud of bees or other insects," Old English swearm, from Proto-Germanic *swarmaz (cf. Old Saxon, Middle Low German swarm, Swedish svärm, Middle Dutch swerm, Old High German swarm, German Schwarm "swarm;" Old Norse svarmr "tumult"), usually derived from PIE imitative root *swer- (2) "to buzz, whisper" (see susurration) on notion of humming sound. But OED suggests possible connection with base of swerve and ground sense of "agitated, confused, or deflected motion."
