noun
Honorific term used in historical or formal contexts to refer to a high-ranking government minister or noble. Not used in modern everyday speech.
昔、大臣はおとどと呼ばれていた。
Long ago, ministers were called おとど.
noun
nobleman's residence
Archaic honorific term for the residence of a nobleman. Rarely encountered outside historical texts.
古文書には、おとどの広大な屋敷が描かれている。
In old documents, the vast residence of the nobleman is depicted.
Modern standard word for 'minister', read だいじん. おとど is an archaic honorific reading of the same kanji.
The reading おとど is an honorific form derived from お (honorific prefix) + とど (possibly related to 殿, meaning 'lord' or 'residence'). The exact derivation is uncertain.
