Middle Korean was a tonal language and Chinese loan words were also starting to be imported during this same time; however, everything I've seen about the tones references native Korean examples. This makes me wonder:
- Did the Chinese words retain their tones during this time? Middle Korean was only three tones, so not a perfect match, but I'm assuming the tones would have survived to a degree.
- If so, do the Korean dialects that retain tones (i.e. Kyongsang and Hamgyong) also retain the tones for any Sino-Korean words?
