I've been studying Korean, on and off, for about 30 years. I also took two semesters of college Japanese (ありがと, benkyo shimash'tanga zenbu wasuremashita).
I'm user #21 here, and user #188 at Wikipedia.
This year, I upgraded my home Internet access, so I've become a lot more active here. My primary interest is Korean vocabulary. 감사합니다.
I'd like to contribute the following Korean words:
First I have to make sure they're not already in the dictionary. Then I have to get them in the right format; maybe a template can help.
Also what about the back-translation from English to Korean?
Look at this Korean word frequency list which is in alphabetical order. The first column looks like some kind of word count. The second column is Korean words.
