Let’s get into some Sino-Korean with the 인 from 인간! 인간 is derived from the Chinese hanja character 人 which means person. This is one if the simplest characters with minimal strokes and it looks like a stick mans legs so it’s easy to remember!
사람 or 인간 Which Do I Use and When?
사람 is the most common way to say person and 인간 has a more formal feel to it. Think of it similar to 사람: person and 인간: human. In most sentences you wouldn’t say “that human is my teacher” you would more naturally say “that person is my teacher”. So you can use it more formal situations such as an educational setting eg. “humans are mammals”.
Is The Character 人 Used by Koreans?
Yes actually the hanja is used a bit in Korean media, news, signs and other places. For example you can see it used here in this poster design:
Anyway lets get into all the 인 words!

Is Sino-Korean Important?
It’s not necessary but it can be useful! I put the original Chinese character in for anyone who would like it but you can basically ignore most characters and focus on the fact 인 in certain words has to do with people and humanity.
