Otiose is a colorful, although somewhat old-fashioned, word for "lazy." It also means serving no useful purpose: that steak knife next to your plate is otiose if you're having oatmeal for dinner.

Otiose, which can be pronounced either with a t sound (OH-tee-ohs) or a sh sound (OH-she-ohs), comes from the Latin word otium "leisure," but its modern meaning is closer to "leisure suit," that is, useless and not very handsome. If you're already wearing suspenders, then a belt is otiose.
