Sensei
Sensei (先生) is a Japanese word, indicating a form of respect, and can have several meanings
- It can be used to address one's teacher.
- Or generally speaking someone strong enough to be a teacher.
- It can also refer to an older player.
The -sensei ending is one example of a Japanese name suffix.
Sidenote: in Hikaru no Go, an older player comes into the club to find 11-year old Akira Toya, a kid aspiring to become a professional Go player. The man asks if Akira Sensei is present. One can imagine that Yoda Norimoto will call Sakata "Sensei", although Yoda is probably stronger at the moment.
