Red-haired or dew
As a standalone name, Ro is often a shortened form of names like Rowan, Roland, or Rosemary. It can derive from the Gaelic 'ruadh' meaning red-haired, or the Latin 'ros' meaning dew. Its brevity makes it a modern, gender-neutral choice that functions as a minimalist nickname-name.
