If you’ve been exposed to Korean language even a little bit, you know that almost every family member has its own term. For example, instead of just saying “aunt,” there are different terms used depending on whether the “aunt” is your mother’s sister, your father’s sister, or an in-law.
A couple of months back The Korea Blog did a post about these family terms titled “Who’s Your Big Daddy?” You find it at this link: http://blog.korea.net/?p=1926
Using graphics and detailed explanations, this entry will answer all your questions and/or possibly confuse you beyond belief. 🙂 But honestly, it’s the best explanation of family terms that I’ve seen. It would be a great one to print out and keep on hand for reference.
