what's the difference between "sedang" and "tengah"?
As far as I know,
they both mean "in the middle of something" or "~ing" in English.
For example,
As for, "what are you doing?",
we can say, "awak sedang buat apa?" or "awak tengah buat apa?".
Both sentences are exactly the same?
or "sedang" is often used in a formal case??
It would be appreciated if you explain this.:)
