The word prefaced by the adjective 大, pronounced "dai" (or "ō"), which means "great" or "large", is often translated "grand master". This compound term, "dai-sensei", is sometimes used to refer to the top sensei in a particular school or tradition, particularly within the iemoto system. For a more senior member of a group who has not achieved the level of sensei, the term is used – note the common use of 先 "before"; in martial arts, this is particularly used for the most senior non-sensei member.
