Is there any way to definitely differentiate between, for example, these two sentences:
neden korkuyor musun? - what are you afraid of?
neden korkuyor musun? - why are you afraid?
...without structuring them differently? Actually, does the latter even work as a complete sentence, or would it require a subject? Or can "neden" be the subject, as in "why is it that you are afraid?" or something like that?
