>>213100186You don't need to guess, even if it's in a picture you can look up Hangul translators that let you click buttons to punch in the characters
Then you just learn to find the sub characters inside the compound characters
They are almost all literal because it's a new system not Chinese bullshit so you just look for characters that match the ones that you can punch in, and then the translator auto combines them as applicable. It's just right to left top to bottom order too.
