   “Jinja” (진짜) is a casual way to say “really” or “truly” in Korean. It can be used as an adverb or an adjective, usually to emphasize that something is real or true. Since it’s an informal word, save it for casual conversations with close friends or people who are younger than you. If you’re speaking to someone older or you’re in a formal setting, use “jeongmal” (정말) to be polite.
