bandit: [16] Etymologically, a bandit is someone who has been ‘banished’ or outlawed. The word was borrowed from Italian bandito, which was a nominal use of the past participle of the verb bandire ‘ban’. The source of this was Vulgar Latin *bannīre, which was formed from the borrowed Germanic base *bann- ‘proclaim’ (from which English gets ban). Meanwhile, in Old French, bannīre had produced banir, whose lengthened stem form baniss- gave English banish [14]. => ban, banish[bandit etymology, bandit origin, 英语词源]
