means A South or Southeast Asian king, prince, or ruler — a title of royal rank that may or may not come with real authority.

from From Sanskrit 'rāja' meaning king, a word with deep Indo-European roots — it's a cousin of Latin 'rex' and the '-reg-' in words like 'regal' and 'regent,' all tracing back to an ancient root meaning 'to rule' or 'stretch in a straight line' (as a ruler sets the standard). The title spread across South and Southeast Asia with Indic culture and language, picked up by Malay, Javanese, and other regional courts, which is why it still shows up in princely titles from India to Indonesia and Malaysia today.
