Origin & History of “thread”

A thread is etymologically something ‘twisted’. The word comes from a prehistoric Germanic *thrǣthuz, which was derived from the base *thrǣ- ‘twist’ (source also of English throw). Other descendants of *thrǣthuz include Dutch draad, Swedish tråd, and Danish traad ‘thread’ and German draht ‘wire’.
