khan

Khan is a historic Turkic and Mongolic title originating among nomadic tribes in the Central and Eastern Eurasian Steppe to refer to a chief or ruler. It first appears among the Rouran and then the Göktürks as a variant of khagan (sovereign, emperor) and implied a subordinate ruler. In the Seljuk Empire, it was the highest noble title, ranking above malik (king) and emir (prince). In the Mongol Empire it signified the ruler of a horde (ulus), while the ruler of all the Mongols was the khagan or great khan. The title subsequently declined in importance. During the Safavid dynasty it was the title of an army general, and in Mughal India it was a high noble rank restricted to courtiers. After the downfall of the Mughals it was used promiscuously and became a surname. Khan and its female forms occur in many personal names, generally without any nobiliary of political relevance, although it remains a common part of noble names as well. Etymology The origin of the term is disputed and unknown, possibly a loanword from the Ruanruan language. According to Vovin (2007, 2010) the term comes from qaγan (meaning emperor or supreme ruler) and was later borrowed and used in several languages, especially in Mongolic and Turkic. A Turkic and Para-Mongolic origin has been suggested by a number of scholars including Ramstedt, Shiratori, Sinor and Doerfer, and was reportedly first used by the Xianbei. According to Vovin, the word *qa-qan "great-qan" (*qa- for "great" or "supreme") is of non-Altaic origin, but instead linked to Proto-Yeniseian *qεʔ "big" or "great". The origin of qan itself is harder according to Vovin. He says that the origin for the word qan is not found in any reconstructed proto-language and was used widely by Turkic, Mongolic, Chinese and Korean people with variations from kan, qan, han and hwan. A relation exists possibly to the Proto-Yeniseian words *qij or *qaj meaning "ruler".
