10-second answer
The short answer
인 (in) comes from 人, meaning "person." It's one of Korean's most productive roots — attach it to a country name and you get a nationality (한국 + 인 = 한국인 / hanguk + in = hangugin, "Korean person"), attach it to a concept and you often get a related noun about people or popularity (인기/ingi = popularity, literally "person energy"). Once you spot 인, a huge chunk of vocabulary about people and nationality stops being memorization and starts being decoding.

인 vs 사람 — both mean "person"
사람 is the native Korean word for "person" and is what you use in everyday speech (저는 한국 사람이에요). 인 is the Hanja root and shows up in more formal, compound, or written vocabulary (한국인, 외국인). They overlap in meaning but aren't always interchangeable — 한국인 sounds slightly more formal/official than 한국 사람.

Nationality Words Are the Easiest Win
Nearly every country name + 인 gives you that nationality: 미국인 (American), 중국인 (Chinese person), 일본인 (Japanese person), 영국인 (British person). Once you know a country's Korean name, you almost always know how to say "a person from there" for free — just add 인.

Common Mistakes
Mistake #1 — Using 인 in casual speech where 사람 fits better
저는 한국인이에요 is correct but slightly formal-sounding; 저는 한국 사람이에요 is the more natural everyday version among friends.
Mistake #2 — Missing that 인기 is about popularity, not personality
인기 (popularity) and 인간 (human being) both start with 인 but mean very different things — check the second syllable, not just the root.
