Madara is Japanese for brave so like if u watch naruto then madara's name is brave uchiha Although it means "brave" in Japanese, madara also means humiliation in Turkish even though these two languages belong to the same language group madara means two different things for them. And we can see the Turkish meaning is more proper as Hashirama arrives and humuliates Madara in the manga series.
