          thread: [OE] A thread is etymologically something ‘twisted’. The word comes from a prehistoric Germanic *thr?thuz, which was derived from the base *thr?- ‘twist’ (source also of English throw). Other descendants of *thr?thuz include Dutch draad, Swedish tr?d, and Danish traad ‘thread’ and German draht ‘wire’.

          thread (n.)

Meaning "spiral ridge of a screw" is from 1670s. Threads, slang for "clothes" is 1926, American English.

[John Leslie, "Elements of Natural Philosophy," Edinburgh, 1823]
          thread (v.)
          "to put thread through a needle," mid-14c., from thread (n.); in reference to film cameras from 1913. The dancing move called thread the needle is attested from 1844. Related: Threaded; threading.
