throw 词源(Etymology) - 趣词词源[英文版]

throw [throw 词源字典]: throw: [OE] Old English thrāwan meant ‘twist, turn’. It came from a prehistoric Germanic *thrējan, which also produced German drehen ‘turn’. This in turn went back to the Indo- European base *ter-, whose other descendants include Greek teírein ‘wear out’, Latin terere ‘rub’ (source of English attrition [14], contrition [13], and trite [16]), Lithuanian trinù ‘rub, file, saw’, Welsh taradr ‘auger’, and English thread and turn.

It is not clear how the original sense ‘twist, turn’ (which survives in ‘throwing a pot’ on a potter’s wheel) evolved in English into ‘project, hurl’ (first recorded in the 13th century), but presumably there must have been some intermediate phase such as ‘throw with a twisting action – as in throwing the discus’.
