Etymology 2

From Old Japanese. Possibly cognate with Korean nominal particle (i).

Used in Old Japanese, still found in use in Chinese works annotated for Japanese readers of Early Middle Japanese in the early Heian period, then becoming more limited and appearing only in specialized Buddhist texts. Fallen into disuse by the late Heian period from the time of so-called “cloistered rule”.[1][2]

Obsolete. Not used in modern Japanese.
