also: おんしょ
noun
Honorific term for someone's writings, used to show respect toward the author. Often used in formal or literary contexts.
先生の御書を拝読しました。
I had the honor of reading your writings, Sensei.
Neutral term for 'writings' or 'works'; 御書 is explicitly honorific.
Compound of honorific prefix 御 (go) and 書 (sho, 'writing'). The reading おんしょ uses the older honorific prefix 御 (on).
