bandit comes from Italian bandito ('outlaw'), literally 'banned, outlawed', past participle of bandire ('to proscribe, banish'), of Germanic origin via the root of ban. The path is chiefly one of transmission: an older form is taken into English, with the word's shape and meaning carried through the language names and forms preserved in the history. In modern use, the noun sense is "a robber or outlaw, typically one of an armed band", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as banish and derivatives such as banditry, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Italian bandito, Italian bandire, which anchor the explanation in named linguistic material.
