My last post got me thinking... marital status and gender are so important in Korean culture, relative to U.S. of American culture. In Migook (Beautiful Country - the Korean word for USA), how you are addressed by the members of your family doesn't really change when you get married and doesn't depend on your gender. In Korea, it changes a lot when a person gets married. Likewise, what you call another person depends a lot on gender, both of the one being called upon, and the one doing the calling.
1. A woman sometimes calls her boyfriend "oppa" (older brother, older male friend) when they are dating, but after marriage, the use of the term "oppa" to call your husband is generally not promoted. One is encouraged to use the word yobo or jaghi instead. If you called your husband oppa in front of your in-laws, you might get a "look" from your MIL or a stern scolding from you FIL. But some in laws might be OK with it too...
2. As brought up by comments in my last post, your father's brothers are called samchon. Your mother's brothers are called wehsamchon. However, if your father's brother is married, he would be called either Big Father, or Little Father. Kunappa or Jakeunappa, depending on his relation (older or younger) to your father. If your mother's brother is married, he is still called wehsamchon. (See how the sexism comes out in the language?)
3. Your father's sister is gomo... and remains gomo even if she got married. I guess in this case, the gomo's marital status doesn't really matter... perhaps since she is a woman?
Anyway, I remember learning about how the Eskimos have tons and tons of words for the different kinds of snow. Same concept. There are so many Korean words that describe your relationship to another person. Not so much in English. I remember learning in an introductory college class about this... how Western culture is much more individualized and Eastern culture is more community based. I wonder how long it takes for language to evolve...
