Bandito is a familiar English word used to refer to a bandit, especially one in Mexico or the American southwest. While it is familiar to most English speakers, especially Americans, it is not a word in common rotation in most people's vocabulary. It came into popular culture by way of the spaghetti western and related media, and stuck around specifically in the context of westerns.

Bandito comes from Italian, being the past participle of bandire, the verb meaning 'to ban' -- a 'bandito' is 'that which is banned'. As such, the proper conjugation would be: female 'bandita', masculine plural 'banditi', and feminine plural 'bandite'. However, we do not do this in English, rather treating bandito as a gender neutral label and using the plural form 'banditos'.

Bandito is often mistaken for Spanish; while a Spanish speaker is not particularly more likely to refer to a wrongdoer as a bandit than is an English speaker, if one were to do so, the Spanish word is bandido.
