Answer warnings and help, as previously mentioned (9)
I believe the answer is:
aforesaid
'previously mentioned' is the definition.
(I've seen this before)
'answer warnings and help' is the wordplay.
I cannot quite see how this works, but
'answer' could be 'a' (abbreviation eg in Q and A) and 'a' is present in the answer.
'help' could be 'aid' (synonyms) and 'aid' is located in the answer.
The remaining letters 'fores' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for aforesaid that I've seen before include "Above-mentioned" , "previously referred to" , "The one previously mentioned" , "earlier" .)
