The noun is derived from Middle English winding, windinge, wyndynge (“directional change, curve, turn; bend of the leg at the knee; meandering course of a river; act of turning and twisting; twisting of things (especially thread) together; wrapping of a cloth around something; wattling of a structure; wattle(s); ornamentation with interwoven patterns; hoisting of something”) [and other forms], and then partly: * from winden, wynden (“to go, move; to move forcefully or suddenly; to direct, guide, lead; to go along a meandering or twisting course; to move in a circular pattern, revolve, turn; to move restlessly, toss and turn; to wriggle free; to move with a turning or twisting motion, bend, turn, twist; to form or mould (something) in one’s hands; to mix together; to cover; to clothe, dress; to wrap (a baby, a corpse, etc.); to encircle, surround; to bind; to interlace; to winch; (figurative) to conceal, disguise; to embroil, involve”) + -ing, -inge (suffix forming gerund nouns, and the present participle forms of verbs).; and * from Old English windung (“woven object”), from windan (“to twist, wind; to circle, curl, eddy, spiral”) (from Proto-Germanic *windaną (“to wind; to wrap”), from Proto-Indo-European *wendʰ- (“to turn; to wind”)) + -ung (suffix forming nouns denoting a verbal action or something involved in a verbal action). The adjective is derived from the verb. The English word is analysable as wind (“to turn coils of (a cord, etc.) around something; to encircle, enfold, entwist, wrap; to travel in a way that is not straight”) + -ing (suffix forming present participial adjectives and verbs, and nouns denoting an action or the embodiment of an action).
