汀理

Noun

 * 1)  riverbank

Reconstruction notes
Per Old Korean orthography, the final syllable was or. Due to a lack of Middle or Modern Korean reflex, the rest of the pronunciation is not reconstructible. The Middle Korean word for "riverbank" was the periphrastic > Modern, which seems to have displaced the Old Korean word.

In order to allow some sort of transcription of Old Korean, Korean scholars in the past century have proposed:


 * A connection to 🇨🇬, which is now generally rejected both on semantic grounds and because the very same poem actually contains the word.
 * Various solutions employing cranberry morphemes, such as in.

By far the most likely explanation is that the Old Korean word simply went extinct and, to quote, "will remain a perennial mystery forever".
