servicio
/seɾˈbiθjo/ · A2 · noun · m
service
🚻 servicio = service; los servicios = the facilities, i.e. the toilets
From Latin servitium (serving), same root as English service, so the spelling is nearly identical. Spanish also uses it as a polite word for a public toilet, much like English says the facilities. Note the middle: -vi- is pronounced bi.
