chaise longue, chaise lounge (n.)
Chaise longue (pronounced in the French way, shez LAWNG) is the borrowed name for that curious combination of chair and daybed, but at a quick glance longue looked much like the English lounge, and given the posture of the person reclining, lounge became folk etymology’s contribution to the name of the artifact, so that some Americans now both spell and pronounce it as an American hybrid, chaise lounge (shez LOUNJ). Both terms are Standard today, but those who know French still take exception to chaise lounge.
