The word "viatica" has its roots in Latin. It comes from the Latin word "viaticum", which is a noun derived from the adjective "viaticus". In Latin, "viaticum" was used to refer to provisions or money given to someone who is about to embark on a journey. It literally translates to "provisions for a journey". Over time, "viatica" has been adapted into English and other languages to refer to religious objects or sacraments given to a dying person to provide spiritual support for their journey into the afterlife.
