Daishi

Daishi (大師) is a Japanese word which means great and/or silent master. It was also used as an honorary title given by the Japanese Imperial Court. The closest English translation for the word in this case would be "great teacher." Two well known recipients are Kūkai (or Kōbō Daishi) and Saichō (or Dengyō Daishi), the founders of the Shingon and Tendai Buddhist sects, respectively.

Daishi in fiction

The BattleTech universe and its related MechWarrior game series have popularized the word Daishi as the Inner Sphere moniker for the Dire Wolf class OmniMech, albeit with the syllable shi in a different context, meaning "death" instead of "teacher."
