Quotes
He had for a moment been very angry when his friend had told him that he could not sympathise with a lackadaisical lover. It was an ill-natured word. He felt it to be so when he heard it, and so he continued to think during the whole of the half-hour that he sat in that chair.
-- Anthony Trollope, The Small House at Allington, 1864
Origin
Lackadaisical stems from the archaic term lackadaisy, a variant of lackaday. These in turn came from an alteration of the phrase alack the day, an interjection used as an exclamation of sorrow, regret, or dismay.
