also: おしずまる
yodan verb with 'ru' ending (archaic)
Archaic honorific verb (sonkeigo) used to refer respectfully to someone sleeping. Found in classical Japanese texts; in modern Japanese, honorific sleep is expressed with お休みになる or お休みあそばす.
古典文学では、「御寝る」は高貴な方の就寝を表す言葉として使われた。
In classical literature, 御寝る was used as a term for the sleeping of a noble person.
The verb およる is an old honorific expression that is hardly used today.
Compound of honorific prefix 御 (お) and classical verb 寝る (now 寝る ねる). The reading およる is a regular sound shift from お + 寝る. The alternate reading おしずまる may derive from a different verb root, but its exact origin is uncertain.
