c.1400 (implied in wrinkling), probably from stem of Old English gewrinclod "wrinkled, crooked, winding," past participle of gewrinclian "to wind, crease," from perfective prefix ge- + -wrinclian "to wind," from Proto-Germanic *wrankjan (see wrench (v.)). Related: Wrinkled.
"fold or crease in the extenal body," late 14c.; in cloth or clothing from early 15c., probably from wrinkle (v.). Meaning "defect, problem" first recorded 1640s; that of "idea, device, notion" (especially a new one) is from 1817.
[origin of first sense unknown; perhaps fr the same semantic impulse as twist in a similar sense, referring to a quick shift in course; perhaps a reference to a lack of plain simplicity in dress or decoration, and the prevalence of stylish pleats, folds, etc, since the earliest form is without all wrinkles; second sense fr the notion of ironing the wrinkles out of something]
