lanyard (n.)

also laniard, "small rope or cord used aboard ships," alternative spelling (influenced by nautical yard (2) "long beam used to support a sail") of Middle English lainer, "thong for fastening parts of armor or clothing" (late 14c.), from Old French laniere "thong, lash, strap of leather," from lasniere (12c., from lasne "strap, thong"), apparently altered (by metathesis and influence of Old French las "lace") from nasliere (nasle), from Frankish *nastila or some other Germanic source, from Proto-Germanic *nastila- (source also of Old High German, Old Saxon nestila "lace, strap, band," German nestel "string, lace, strap"), from PIE root *ned- "to knot."
