Metehan
Metehan is a common masculine Turkish given name. "Metehan" is composed of two words: "Mete" and "Han". In Turkish, "Mete" means "brave", "galahad", "hero", "valiant", and/or "gallant" whereas "Han" means literally "Khan". Thus, "Metehan" means "brave khan", "galahad khan", "gallant khan".
Mete is a deformed version of "Mo - du" which is the regnal name of Modu Chanyu who was the founder of Xiongnu Empire. Mete is considered one of the first known Turkish rulers in the history and the name is used in memory of him. Appropriate Turkish reading of "Mo - du" is " Baghatur". Baghatur is also used as a masculine given name by Turkish people as Bahadır, Batur, and as in other cognate forms.
