Sensei

Sensei, also known as Seonsaeng, Tiên sinh or Hsien sheng/Xiansheng (corresponding to Chinese characters 先生), is an East Asian honorific term shared in Japanese, Korean, Vietnamese and Chinese; it is literally translated as "person born before another" or "one who comes before". In general usage, it is used, with proper form, after a person's name and means "teacher". The word is also used as a title to refer to or address other professionals or people of authority, such as clergy, accountants, lawyers, physicians and politicians or to show respect to someone who has achieved a certain level of mastery in an art form or some other skill, e.g., accomplished novelists, musicians, artists and martial artists.
