Although it is not a typical Spanish word, it is a voice known by Brazilian influence, where it is used as a greeting, good wishes. Its origin appears to be Bantu, brought to America by African slaves, or perhaps a bad pronunciation of "salve" or "save", used as a desire for "luck" or "health". A curious fact: in Japan existed during the EIGHTEENTH century a greeting that sounded "Sara", "or Sara" or "taken out", but have not found a contact with Saravá.
