Historically, from Medieval Latin bannimus (“we banish, we expel”), from bannō, bandō (“denounce, ban, bannish, proclaim, proscribe”, verb), influenced in meaning by bannum (“ordinance, ban”), from Frankish *bannjan (“to proclaim, order or prohibit under penalty”), from Proto-Germanic *bannijaną (“to curse, damn”), *bannaną (“to request”), from Proto-Indo-European *bhā- (“to say, speak”). Cognate with Old High German bannen (“to order under penalty, proscribe, cast a spell on”), Old High German ban (“order under penalty”). More at ban.
- A form of expulsion of any individual from the University of Oxford, by putting the proctorial edict up in some public place, as a denunciation or promulgation of it. It also served to prevent the individual from claiming the cause of expulsion.
