[From lackadaisy, alteration of lackaday.]

lack′a·dai′si·cal·ly adv.
Usage Note: The first two syllables of lackadaisical are pronounced (lăk′ə). Some people use the pronunciation (lăk′sə), as though the word were spelled lacksadaisical or laxadaisical. The confusion is probably semantic—someone who is lackadaisical could be said to have a lax attitude. In our 2014 survey, the Usage Panel overwhelmingly preferred the traditional pronunciation. Only 12 percent of the Panel found the lax pronunciation to be acceptable, and only 6.5 percent reported that they use it as their own preferred pronunciation.
