way easier than learning chinese characters. Chinese characters are just the practice of torturing yourself until you remember them. Its frankly amazing that Chinese even functions at all considering how bad the language is.
I feel like this happens with almost any language (of course, English being the exception). As a native Spanish speaker, I was told since we were kids that learning to pronounce Spanish had absolutely no complications. Similarly happened when I started learning German, you do need to learn about the diphthongs, but I believe those are the only exception. Then I took Chinese, the characters are hard but no syllable will take you by surprise. Even when I went on vacation to Greece, I decided to learn the Cyrillic alphabet to make asking for directions to places (and reading traffic signs) easier, and it was a piece of cake!
Not really Katakana, it’s more like western word of Korean, if I were to relate Korean to Japanese, katakana version of Korea is the same as the hiragana version in spelling.
I never expected an idiomatic language like Korean to be phonetic. I assumed every composite symbol had its own pronunciation you had to individually learn.
