winding

The noun is derived from Middle English winding, windinge, wyndynge (“act of exposing something to the wind, airing, ventilating; act of winnowing (?)”), from winden, wynden (“to expose (something) to the air or wind, ventilate; to cause (someone) to be out of breath; to winnow (wheat); of an animal: to catch the scent of (someone or something)”) + -ing, -inge (suffix forming gerund nouns, and the present participle forms of verbs).

The adjective is derived from the verb.

The English word is analysable as wind (“to blow air through (a wind instrument or horn) to make a sound; to cause (someone) to become breathless; to winnow (food grain), etc.”) +‎ -ing (suffix forming present participial adjectives and verbs, and nouns denoting an action or the embodiment of an action).
