So this basic phrase is very simple to learn and easy to use (in the right situation of course ;p)
We wanted to touch a bit more on this topic as we have already done two graphics about love related vocabulary (Terms of Endearment and Dating terms). As you can see, there are quite a few ways to express how you feel about someone aside from just I love you. There are actually several more that we may touch on in the near future so this may be a part 1.
Like most cultures, Koreans celebrate birthdays. Although they calculate age a bit differently (look forward to a post on that in the future), they have birthday parties, sing happy birthday, and enjoy the time with their friends and families.
미역국 is traditionally eaten on birthdays here, and many feel it is not a complete birthday without it.
These are the common and casual ways of what roughly translates to good luck in Korean. Some Korean books explain these really well. You have probably heard “화이팅” (also sometime 파이팅/fighting) on dramas or just around your Korean friends. The other two are also very common and used among close people and friends. Like telling someone to have a good day, you want to send your friends off with a good feeling of confidence to accomplish whatever it is they need to accomplish.
