Forms: 1500s–1800s ponton, 1600s– pontoon, 1700s pontoone.

Origin: A borrowing from French. Etymon: French ponton.

Etymology: < Middle French, French ponton a bridge (c1245 (or earlier) in Old French), a draw-bridge (a1370), a flat-bottomed boat (late 14th cent.; perhaps attested earlier (1251) although the precise sense of this occurrence is unclear), a floating bridge made up from a number of boats (1532) < classical Latin pontōn- , pontō flat-bottomed boat, ferry, punt < pont- , pōns bridge (see pons n.) + -ō (see -oon suffix). Compare pont n.² and earlier punt n.¹There is some uncertainty about the precise meaning of the word in classical Latin (and post-classical Latin), and hence about the semantic relationship with pōns.

a. Chiefly Military. Originally: †a bridge (obsolete). Later: spec. a temporary floating bridge supported by a number of boats, hollow metal cylinders, or other floats. Also figurative.
