>Refusing to obey or respect the law in a way that shows contempt:
The Latin adjective contumax means “rebellious,” or, in specific cases, “showing contempt of court.” Contumacious is related to contumely, meaning “harsh language or treatment arising from haughtiness and contempt.” Both contumacious and contumely are thought to ultimately come from the Latin verb tumēre, meaning “to swell” or “to be proud.”
