I found out it's very hard for non-Koreans to learn Korean.
What is the most difficult part in learning Korean?
José, you can make that sound almost without moving your lips^^ Try to lower the tongue to make the inner of the mouth to about that shape :)
As for me, it was definitely the grammar. Woah. This sentence structure. And not just the basic word order, or your adjectives (descriptive verbs), but it's not exactly getting easier later, when you get verb tenses and later to noun groups. All basic ideas about what a sentence IS seem to be different in Korean when compared to Romance or Germanic languages.
Learning new words is also not easy for a long time. When you learn French and you know English a bit, then you have a lot of familiar words, and that helps a lot! But you have no familiar words with Korean. It took me two years before I was at the point where I can learn new vocabulary more easily because it reminds me of other Korean words. (Hint: For me, it helps to use the look of a word. "First a horizontal vowel, second a vertical one." I can remember it a lot better this way.)
Another difficulty are words that have no translation in any language that I know. I had to do this for about a year until it was getting easier. You have to get used to regularly invent a new meaning in your head, a meaning that you have never used before, and then stick the new sound to this meaning.
That being said -I love your language.
Plus, I enjoy hangeul.
Ah, but I make things sound pretty hard now.
Using the language once you understood how to do it is a lot easier than in so many other languages.
Making new forms is so simple! Both nouns and verbs. All words are so nice. They just do what you want.
