Etymology

It is Middle English swimmen, inherited from Old English swimman (“to move in or on the water, float”),[2][3][4][5] from Proto-Germanic *swimmaną,[3][2] cognate with Old Saxon swimman, Dutch zwemmen, German schwimmen and Old Norse svimma,[2][3] perhaps from PIE Proto-Indo-European *swem- (“to be in motion”).[3][2]

Earliest recorded meaning

To move in water: Old English, about 725, in Beowulf.[2][6]

Semantic evolution

To cross by swimming is from the 1590s.[3] Sink or swim is from the early 15th century,[3][6] and swim with the tide by the 1590s.[3] Of things seen by a dizzy person, to reel, is from the 1670s, and of the head, to feel dizzy, from 1702, perhaps influenced by Old English swīma (“unconsciousness”).[3] The noun meant the clear part of a liquid (1540s), and an act of swimming from 1764.[3][7] A stretch of river frequented by fish is from 1828, which probably gave in the swim, in the current of events (late 19th century).[3][6]
