Fix back cover on old novel (7)
I believe the answer is:
dilemma
'fix' is the definition.
(I've seen this in another clue)
'back cover on old novel' is the wordplay.
'back' shows that the letters should be reversed in order.
'cover on old' becomes 'lid' (I can't justify this - if you can you should give a lot more credence to this answer).
'novel' becomes 'Emma' (novel by Jane Austen).
'lid' written backwards gives 'dil'.
'dil'+'emma'='DILEMMA'
Can you help me to learn more?
(Other definitions for dilemma that I've seen before include "embarrassment" , "Difficult-choice situation" , "Difficulty (with two choices?)" , "The choice between courses of action, all equally undesirable" , "tricky position" .)
