词源

From Middle English threschwolde, threscholde, from Old English þresċold, þerxold, þrexwold (“doorsill, entryway”), from Proto-Germanic *þreskudlaz, *þreskūþlijaz, *þreskwaþluz, from Proto-Germanic *þreskaną, *þreskwaną (“to thresh, (originally) to tread”), from Proto-Indo-European *terh₁- (“to rub, turn”). Cognate with Low German Drüssel (“threshold”), dialectal German Drischaufel, Drissufle, Trüschübel (“threshold”), Danish tærskel (“threshold”), Norwegian terskel (“threshold”), Swedish tröskel (“threshold”), dialectal Swedish träskvald (“threshold”), Icelandic þröskuldur (“threshold”). Pronunciations such as “thresh-hold” are un-etymological and result from analogy with hold.
