Korean is not a hard language to learn. It actually requires less grammatical rules than English, which is a very complex language. It's harder to learn for an English speaker than say, Spanish or Italian, just because it's not a branch of Latin like the European languages.

Korean borrows a lot of words from English too! Radio, robot, camera, coffee, all are basically the English word with a Korean accent.

One of the hard parts of Korean is knowing the formal way of speaking to elders. It's not just a different verb tense like with some other languages. Often there are different words you use.
