古英語のthrescan「叩く」「脱穀する」「踏む」から、原語ゲルマン語*threskan「踏む」「脱穀する」、PIE*tere「曲げる」「回す」「挽く」から、語源的にはturn「回す」throw「投げる」と同じ。

thresh (v.)

Old English trescan, terscan, "to beat, sift grain by trampling or beating," from Proto-Germanic *threskan "to thresh," originally "to tread, to stamp noisily" (cognates: Middle Dutch derschen, Dutch dorschen, Old High German dreskan, German dreschen, Old Norse treskja, Swedish tr?ska, Gothic triskan), from PIE root *tere- (1) "to rub, turn" (see throw (v.)).

The basic notion is of men or oxen treading out wheat; later, with the advent of the flail, the word acquired its modern extended sense of "to knock, beat, strike." The original Germanic sense is suggested by the use of the word in Romanic languages that borrowed it, such as Italian trescare "to prance," Old French treschier "to dance," Spanish triscar "to stamp the feet."
