This is a day late but 메리 크리스마스 여러분!
Don’t worry I come with gifts~
I recently found a chart of punctuation marks with their Korean equivalent names here. This is something that could be useful, of course you don’t have to memorize all of them; I only picked out the ones that I found the most important such as the exclamation point, the question mark, the period, @ symbol and the + and = signs. Coincidentally, an hour after looking at this chart I watched the first episode of 1997 응답하라 and looking at those words was the main reason I was able to understand the second half of the episode!
Bye for now~
