extranjero
/eɡstɾanˈxeɾo/ · A2 · adj
foreign
🛂 extranjero = extra + -ero: one from outside; cousin of English stranger
From Latin extraneus (outside, external) via Old French estrangier, the same source as English strange and stranger. The extra- at the front means outside, so an extranjero is literally an outsider: someone or something from another country.
