Rough end absorbed by outstanding city (6)
I believe the answer is:
dundee
'city' is the definition.
(I've seen this before)
'rough end absorbed by outstanding' is the wordplay.
'rough' indicates an anagram.
'absorbed by' means one lot of letters goes inside another.
'outstanding' becomes 'due' (I've seen this before).
'end' anagrammed gives 'nde'.
'nde' placed within 'due' is 'DUNDEE'.
(Other definitions for dundee that I've seen before include "Scottish city with cakes" , "Tayside city, Dens Park team" , "Crocodile -; - cake" , "City in Scotland and a cake" , "Scots city of cake fame" .)
