Languages-learning as a hobby, so this is all I do on my day of rest =) Learning Korean is so-ooo hard, especially when involving sound changes. Just like reading Al-Quran when you need to change the way you pronounce the words due to alphabet like م MIM meet the ﻥ NUN and KAF that it becomes MIN'g.. they have it too in certain cases like when T meet the M alphabet in moT Meok kko (can't eat) , the T will become N that change the sentence to moN Meok kko.

Besides, they also have this polite (honorific) and plain kind of speech. In Bahasa Melayu, we change the noun AKU  as for speaking with friend to SAYA to show respect to someone older or for formality. In Korean, they kinda change the whole words instead of just changing the way they speak of them self. They also use different words for conveying the tense, statement, question and command. As for Mandarin, the hardest part is just the tone and remembering the writing.. yet not as tough as Korean.. waaaaaa
