Which is correct "above question" or "question above"? "Above mentioned" or "mentioned above"?

Question

I would like to know which is more correct: "above question" or "question above"? "Above mentioned" or "mentioned above"?

I have already read different explanations and I cannot understand which one is the most correct?

Many thanks

Answer 1

Both are equally correct. "Above" is both an adjective and a preposition.

"Read the above question."

Here we have used "above" as an adjective that describes "question."

"Read the question above."

Here we have used "above" as a preposition that indicates the position of the "question."

The tricky one is its opposite "below." Whereas "below" is a preposition, it is not an adjective. We can only say:

"Read the question below."

However, we cannot put "below" before the noun. We cannot properly say, "Read the below question."
