noun
Archaic honorific noun for sleep or rest, used in classical or highly formal contexts to refer respectfully to someone's sleep. Not used in modern everyday speech.
古典文学では、貴人の眠りを「御寝」と記すことがある。
In classical literature, a noble person's sleep is sometimes written as 御寝.
Compound of honorific prefix 御 (お) and 寝 (ぬ/る, sleep), with the reading よる possibly from an old verb form. The exact derivation is uncertain; the word is archaic and rarely used in modern Japanese.
