Learn Korean at PBC Languages: A Guide for Chinese Speakers

If you speak Simplified Chinese, you're starting Korean with a real head start on vocabulary. Around 60% of Korean words come from Sino-Korean roots, so once you learn the sound shift, words open up on their own: 문제 (wèntí, problem), 위험 (wēixiǎn, danger), 가능 (kěnéng, possible) land almost identically to their Chinese counterparts. Some go further and trick you in a useful way — 시작 (start) and 开始 use the exact same two characters in reverse order, same with 소개/介绍 (introduce) and 언어/语言 (language). Once you notice the pattern, you start guessing correctly more often than not.

What trips people up is the sound system and a handful of false friends. Korean has a three-way consonant split — plain, tense, and aspirated (ㄷ/ㄸ/ㅌ, ㄱ/ㄲ/ㅋ) — and Mandarin only distinguishes two of those, so the tense sounds (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) need dedicated ear training, not just repetition. Vowels like ㅓ and ㅡ also don't exist in Mandarin and get flattened into 'o' or 'u' sounds if nobody corrects you early. And watch the fake cognates: 공부 (to study) is not 功夫 (martial arts), 애인 (boyfriend/girlfriend) is not 爱人 (spouse in Chinese), and 약속 (promise, appointment) is the opposite mood of 约束 (to restrict).

Grammatically, Korean is SOV with particles doing the job word order does in Mandarin — 이/가, 은/는, 을/를 mark subject, topic and object, and Mandarin has no direct equivalent, though its topic-comment habit (talking about 'this thing, I already did it' style) means the concept of a topic marker isn't totally foreign, just the tool is new. Where you'll move fast: reading. Hangul is phonetic and takes a couple of weeks to read fluently, and once you're past that, Sino-Korean vocabulary means formal and written Korean often makes more sense to you, on first pass, than it does to a native English speaker starting from zero.
