lackadaisical

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 eighteenth century from the interjection lackaday, which was an old fashioned way of saying "oh man!" or "unfortunately."
