More work in university subject with top grade for college (6)
I believe the answer is:
utopia
'more work' is the definition.
(work by Sir Thomas More)
'university subject with top grade for college' is the wordplay.
'university subject' becomes 'topi' (I can't justify this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'top grade' becomes 'A' (top academic grade).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'college' becomes 'u' (abbreviation for University).
'topi'+'a' is 'topia'.
'topia' after 'u' is 'UTOPIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for utopia that I've seen before include "Sir Thomas Moore's perfect society" , "Eden" , "More's perfect society on an imaginary island" , "Heaven" , "Sir Thomas More's perfect place" .)
