Which languages do you speak or read? If you know multiple languages, why did you learn more than just your native language? If you could learn another language fluently, which would it be and why?
At one point I spoke fluent German, Classical Latin, some elementary Russian, and a smidge of French. In fact, I almost became a linguist. (Once I've got my German firmed up a bit, I'm going to resume learning Japanese.)
I learned foreign languages because language fascinates me. It's probably no coincidence that the one constant for the past thirty-odd years has been my career as a writer and editor, no matter what else I was doing to make a living.
