Etymology

It is inherited from Middle English floten, inherited from Old English flotian (“to rest on the surface of water”),[2][3][4][5] from Proto-Germanic *flutōjanan,[2] cognate with Middle Dutch vlōten, Old Saxon flotōn and Old Norse flota,[2][4][3] and formed from the same base as flēotan (“to flow, float”) (see fleet),[2][4][5] from Proto-Indo-European *pleu- (“to flow”).[3] In Middle English it was reinforced by Old French floter, itself of Germanic origin.[2][4][6] The noun merges flota (“boat, fleet”), flote (“troop, flock”) and flot (“sea”).[3][5]

Earliest recorded meaning

The verb, to rest on the surface of water: 1031, in the Anglo-Saxon Chronicle.[2] The noun, the action of floating, is from before 1000.[7]

Semantic evolution

To drift or hover passively is from about 1300,[3] and the noun was used for an attachment that keeps a fishing line afloat from about 1300 and for a raft from the early 14th century.[3] Movement through the air is from the 1630s,[3] and the transitive senses, to make something float (about 1600) and to launch a financial venture (1778), followed.[3] A parade float, from 1888, probably comes from the sense of a flat-bottomed boat (1550s).[3] A soft drink with ice cream floating in it is attested by 1915.[3] A floating rib, not joined in front, is so named by 1802,[3] and the floating of a currency from 1971.[7] In Caithness a float was a strip of ploughed land between two open furrows.[8]
