Derviş is the Turkish and Bosnian (Derviš) spelling of the Persian and Arabic word "darwīš" (درويش), referring to a Sufi aspirant.
The word appears as a given name and surname in various forms throughout Arabic, Bosnian (a Slavic language), Persian, and Turkish-speaking communities.
An etymology for the name is given in the Oxford Dictionary of American Family Names: Status name for a Sufi holy man, from Persian and Turkish derviş ‘dervish’, a member of a Sufi Muslim religious order, from Pahlavi driyosh meaning ‘beggar’, ‘one who goes from door to door’.
