I was wondering if any of you guys know Korean. I want to try to learn it but I want some recommendations from any of you who know the language and/or learning it.

Whenever I try to go and learn it they only teach phrases. But not actually getting your hands on it.

So any book's, apps, websites, tips or anything else would be helpful!
