It will be a while before I get to posting regularly, now that I'm transferring to a new country, trying to find housing, and getting ready for grad school.
I thought I'd mention an interesting linguistic note I observed in a student. A Korean-American high school kid who grew up in the US mentioned to me that he and his sister often add '-ing' and '-ed' tense markers to Korean sentences. For example, "I'm studying" could be "난 공부해-ing".
