며칠

Etymology
from +. The modern form reflects a regular vowel shift after sibilants.

However, the great majority of Korean speakers today believe that the word is from +, connecting it to a Sino-Korean word common in Modern Korean rather than the etymologically accurate but no longer productive Proto-Korean form. Accordingly, is a very common misspelling.

Noun

 * 1) how many days?
