sensei
A respectful title for a Go teacher or instructor.
In Go, sensei means a teacher or instructor who teaches the game. It is used when addressing or referring to that person respectfully, rather than simply identifying someone who happens to give advice.
The term identifies the teacher within an instructional or teacher–student relationship. A sensei may therefore be the person from whom a player receives formal or ongoing instruction, while the title itself emphasizes the respect given to that teacher.
