twinkle v.

derivational suffix, also -le, used mostly with verbs but originally also with nouns, "often denoting diminutive, repetitive, or intensive actions or events" [The Middle English Compendium], from Old English. Compare brastlian alongside berstan (see burst); nestlian (see nestle) alongside nistan). It is likely also in wrestle, trample, draggle, struggle, twinkle, also noddle "to make frequent nods" (1733). New formations in Middle English might be native formations (jostle from joust) with this or borrowings from Dutch.

c. 1400, in phrase in a twynk of oon eye "suddenly, almost instantaneously," from twink (v.) "to wink," probably from Old English twincan (see twinkle (v.)). Meaning "a twinkle" is from 1830. Meaning "young sexually attractive person" is recorded from 1963, probably from Twinkie; but compare 1920s-30s British homosexual slang twank in a similar sense.

snack food, supposedly invented and named 1930 by Jimmy Dewar, baker for the Chicago branch of Continental Baking Co. (later Hostess); said to have been inspired by twinkle.
