Lackadaisical was Oxford Dictionaries Online’s word of the day today. It was defined as “lacking enthusiasm and determination; carelessly lazy”. The word has an interesting etymology. The OED’s first definition is “Resembling one who is given to crying ‘Lackaday!’”. Lackaday is no longer said these days, but it comes from the phrases ‘alack-the-day!’ or ‘alack-a-day!’, interjections with the sense ‘Shame or reproach to the day!’ or ‘Woe worth the day!’. Juliet’s nurse, in Romeo and Juliet, says “She's dead, deceased, she's dead; alack the day!”, when she finds her mistress dead. These phrases are based on the word ‘alack’ meaning pity or shame.
