tiddlywink · noun, verb2
The noun is possibly derived from tiddly (“(informal) little, tiny”) + wink (“blinking of one eye”), perhaps borrowed from etymology 1. The game, now called tiddlywinks, was patented by a British bank clerk, Joseph Assheton Fincher (1863–1900), on 19 October 1889, and the name Tiddledy-Winks trademarked by him the same year. The verb is derived from the noun.
