Hi,
I'm curious... In beginner lesson 14 an alternate (non-textbook) form of "where are you from" is given (doko kara kimashita).
Since this is a question, why is there no "ka" at the end (i.e. doko kara kimashita ka)? Is that a legal use of ka that is simply being omitted due to colloquial speech, or is there a reason why ka is not appropriate for this kind of question?
Thanks!
