jungsuk is the Korean word for joseki.
I think this should be romanised as jungseok. Charles
Alex Weldon: One of the problems with the Korean language is that there are three different vowels that are sometimes romanized as "u." The only one which is "correct" to romanize is the one that looks like a fat T, and which is pronounced like "u" in "flute". The others are -| (pronounced like the "u" in "hung"), which should be romanized as "eo" and -- (pronounced sort of like the "eu" in the French word "peu," closest English equivalent maybe "u" in "put"), which should be romanized as "eu."
So, if Charles' romanization is correct (probably is), the word would be pronounced like "joong sock."
Perhaps jungseok should be added as an alias for this page.
Charles Just checked - it's the -| vowel in both cases, so jeongseok or even cheongseok.
