Especially in east geography (middle east, middle asia, asia) the words starting with Kha, ka, cha means like a leader or a king or a lord.
Khaalesi (game of thrones character who living in east of the game of thrones map)
Khan (old Turkic-Mongolian word e.g. Genghis Khan)
Kaan (old Turkish leaders e.g. Bumin Kaan/Kağan, Kağan)
Is this sound meaning anything like leader or lord ?
