Buenas noches

[Luis Fok]

Spanish for Good night or Good evening.
Buenas noches can be used as a greeting or a farewell. The singular, [Buena] noche, is usually used only in farewells or to describe a night, e.g. Hace una [buena] noche (Its a [nice night]).
It literally means Good nights. This may come from Buenas noches nos dé Dios, translated as, May God give us good nights.
