한국어 문법: 인 particle and others Can someone help me deconstruct the following sentence: 한국은 과거엔 구한국인 대한제국과 구별하여 신한국이라고도 불리기도 했다. I understand the general meaning, but I don’t understand why the following constructions are used: 1. 구한국인 대한제국: what’s the function of particle 인 here. I understand something by the lines of “the Korean Empire in old Korea”. 2. 구별하여: Why the 하여 conjugation in this position of the sentence. 3. 신한국이라고도 불리기도: why 도 is used two times and why the form 불리기 of the verb 불리다. 감사합니다! 🙏
