Review articles discussed works of fiction (7)
I believe the answer is:
analyse
'review' is the definition.
(I know that review is a kind of analyse)
'articles discussed works of fiction' is the wordplay.
I cannot really see how this works, but
'articles' could be 'ana' ('an' and 'a', English indefinite articles) and 'ana' is found within the answer.
The remaining letters 'lyse' 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).
Can you help me to learn more?
(Other definitions for analyse that I've seen before include "Break down to find the constituents" , "Dissect" , "Examine the parts in detail" , "Resolve into components" , "Break down into constituent parts" .)
