"The first wine is very sweet."
Translation:첫 번째 와인은 많이 답니다.
Like in English where first, second, third dont really sound like their numbers... Same here with first in Korean. 번째 is like a counter for 1st 2nd 3rd etc. Similar to how 대 is the counter for machines etc. So for most numbers you take the base number (actual Korean numbers not sino Korean) and add 번째. Eg. 열 번째 = 10th. 다섯 번째 =5th. Numbers 2 through 4 get changed as they do for all counters. 2 = 둘 2nd = 듀 번째 3 = 셋 3rd = 세 번째 4 = 넷 4th = 네 번째 Number 1 is the only one that gets changed completely. 1 = 한나 1 with counters = 한 1st = 첫 번째. Another useful one is 몇 번째 which is used in questions. Like "what place did he come in the race?" or "what place is he in line?"
I hope that makes sense. And i apologise for any dodgy spelling. If i close the app to check then my practice session closes and i lose my comment.
