pīsäl

Uncertain. Possibly from Proto-Indo-European *pésl̥, an l-stem noun derived from the (tentative) root *pes- (“to blow”) (compare Proto-Slavic *paxati (“to sweep”), Old Norse fǫnn (“snowdrift”)), thus meaning originally “that which is blown away”; compare especially Old High German fesa (“chaff”) from the same root. Or alternatively cognate with Sanskrit बुस (busa, “chaff, refuse grain; rubbish”) and perhaps Latin furfur (“chaff, bran; flaky skin”), from Proto-Indo-European *bʰus-, but with phonetic difficulties.
