올빼미

Etymology
Middle Korean is also attested, though late in the sixteenth century and probably an early reflection of the merger of coda  and.

🇨🇬 shows that the word is etymologically equivalent to *옫밤 + nominal suffix, but the meaning of the root is not clear. Speculatively connected to and, i.e. "the thing that cries at night".

Noun

 * 1) owl (without ear tufts)
 * 2) The tawny owl.
