Lackadaisical is an adjective which means listless, dull, without enthusiasm, lazily careless. The adverb form is lackadaisically. Lackadaisical comes from an old expression of regret, lack-a-day! Lack-a-day! is a short form of alack-the-day! The medieval alack means failure, fault, reproach or shame, alack-the-day meant shame-to-the-day! This woeful cry lost its strength over the years until it was merely a mild oath concerning minor things. In the eighteenth century the word lackadaisy popped up to refer to someone who cried lack-a-day! too frequently. At first, when the adjective lackadaisical appeared it meant a person who was weak with sentimentality. Eventually, lackadaisical came to mean an affected demonstration of being slain with emotion, and eventually, simply to mean laziness.
