means To bend, twist, or distort something out of its true shape — or, in weaving, the lengthwise threads stretched on a loom through which the crosswise threads are woven.

from From Old English 'weorpan,' meaning to throw or cast, related to Old Norse 'verpa' and a wider Germanic family of words about throwing and twisting. The weaving sense — threads 'thrown' across the loom — came first; the idea of bending out of shape grew from it, since stretched threads can pull and distort. The science-fiction 'warp speed,' bending space itself, is a much later borrowing of that same notion of distortion.
