Answer having put question raised for writer (5)
I believe the answer is:
aesop
'writer' is the definition.
(ancient Greek writer of fables)
'answer having put question raised' is the wordplay.
'answer' becomes 'a' (abbreviation eg in Q and A).
'having' says to put letters next to each other.
'put question' becomes 'pose' (I can't explain this - if you can you should give a lot more credence to this answer).
'raised' says the letters should be written backwards (going up in a down clue).
'pose' backwards is 'esop'.
'a'+'esop'='AESOP'
'for' is the link.
Can you help me to learn more?
(Other definitions for aesop that I've seen before include "A classical fable teller" , "Fabulous writer" , "Greek fable writer" , "So ape the writer of fables" , "satirical writer" .)
