Etymology
Origin of lackadaisical
First recorded in 1760–70; lackadais(y) (variant of lackaday ) + -ical
Explanation
Even though lackadaisical sounds like it has something to do with a shortage of daisies, know that what it really means is lacking in spirit or liveliness. A person with a lackadaisical attitude shows no enthusiasm and puts forth a half-hearted effort. But it's more of a dreamy, laid back approach rather than sheer laziness. This funny-sounding adjective came about in the 18th century from the interjection lackaday, which was an old-fashioned way of saying "oh man!" or "unfortunately."
