To remove from a cabinet or to dismiss from a government cabinet.
From 'dis-' (to remove) plus 'cabinet,' from Italian 'gabinetto' (small room). The term emerged when European governments formalized cabinet systems in the 17th-18th centuries.
This ultra-rare political term shows how English can theoretically form verbs from any noun, but most such creations die out—'discabinet' never made it while 'dismiss' became the standard term for removing officials.
