이 高層 建物은 摩天樓예요
What is a high-rise building?
Why does pronounciation of the skyscraper part doesn't seem to match the writing?
It's probably because of the 받침. 받침 is the ending consonant on a syllable, there a few rules of pronounciation when it comes for that. In this case, the ㄴ + ㄹ turns into a double ㄹ, so 마천루 is pronounced as /마철루/
in english 'high-rise' and 'skyscraper' are interchangeable to the vast majority of people. are the korean words 고층 건물 and 마천루 ?
