Chinese vs Korean
Is Chinese easier than Korean?
Chinese and Korean are unrelated, but Korean absorbed a large Sino-Korean vocabulary that once was written in Chinese characters (Hanja). Grammar and sound systems differ sharply: Chinese is tonal and analytic, Korean is non-tonal and agglutinative.
The short answer
Korean is easier to start because Hangul is phonetic and there are no tones, while Chinese grammar is simpler, with no conjugation or particles. By intermediate level the difficulty evens out: Chinese has characters to memorise, Korean has speech levels and long verb endings.
The verdict
Both are FSI Category IV (about 2,200 hours). Korean is easier to start reading thanks to Hangul; Chinese grammar is simpler.
