One who crosses separate threads until they hold as one cloth. The weaver adds nothing but the crossing, and the crossing is everything.
Old English wefan (to weave), from Proto-Germanic *webaną, from Proto-Indo-European *webh- (to weave, plait); the agent noun webba (weaver) is attested early. The same root gives WEB and WEFT. Weaving is among the oldest named crafts, and its vocabulary supplies the metaphors of TEXT and TEXTILE alike — both from Latin texere, to weave, which is a separate root arriving at the same idea.
One who makes a whole cloth from separate threads, where the strength is in the crossing rather than in any single strand. The text/textile pair is the point: writing and weaving have been the same metaphor in every language that has both, because both are structure made from sequence.
