scarf: English has two words scarf. The older, but now less frequent, is ‘joint between two pieces of wood’ [14]. This may have been borrowed from an Old French *escarf, which itself was possibly based ultimately on a Scandinavian source (Swedish has skarf ‘joint between pieces of wood’). The scarf that is worn [16] comes from Old Northern French escarpe. This was equivalent to central Old French escarpe, escherpe, which originally denoted a ‘pilgrim’s bag hung round the neck’. It came via a Frankish *skirpja from Latin scirpea ‘basket made from rushes’, a derivative of scirpus ‘rush’. [scarf etymology, scarf origin, 英语词源]
