Archaic polite euphemism for sushi, using the 'o-...-moji' pattern to avoid direct mention. Cross-referenced with 鮨. Not used in modern Japanese.
See also: 寿司
The term '御す文字' can be found in Edo-period documents.
「おすもじ」は、かつて寿司を上品に言い換えた言葉だ。
'おすもじ' is a word that was once used as a refined way to refer to sushi.
Derived from the 'o-...-moji' pattern of polite euphemism, applied to the reading of 鮨 (すし). The exact historical derivation is uncertain, but it follows a known pattern of courtly or women's language in pre-modern Japanese.
