master of the priests' quarters
Historical term referring to the head monk or supervisor of a priests' living quarters within a Buddhist temple complex. Rare in modern usage outside historical or literary contexts.
The name of the master of the priests' quarters is recorded in the old temple documents.
Compound of 坊 (ぼう, 'priests' quarters') + の (possessive particle) + 主 (あるじ, 'master'). The reading あるじ for 主 is an older, now less common reading meaning 'master' or 'head of a household'.
