Playfully joking; making clever little jokes to amuse people. A waggish person teases in a light way that is meant to entertain, not to hurt. It can describe the person ('a waggish uncle'), or the thing they say or do ('a waggish comment', 'a waggish grin'). The joking it points at is mischievous and dry rather than silly — closer to teasing than to telling funny stories. You should know that this word is old-fashioned and quite literary now. Real people in Taiwan, or in London, almost never say it out loud; you meet it in novels, in book reviews, and in newspaper writing that is being a bit playful itself. Modern speakers would say 'jokey', 'cheeky', or 'a bit of a joker'. So it is a good word to recognise, and a risky word to use — using it in ordinary conversation makes you sound like a character in a nineteenth-century book. It comes from the old noun 'wag', meaning a person who is always joking.

愛開玩笑的、詼諧逗趣的（帶點頑皮、揶揄）。這個字現在很文謅謅，多見於小說或書面，日常英語幾乎不用；口語會說 jokey、cheeky。
