Fought lewd comic pinching rump (8)
I believe the answer is:
wrestled
'fought' is the definition.
(I've seen this before)
'lewd comic pinching rump' is the wordplay.
'comic' indicates an anagram (an unusual or comical spelling).
'pinching' means one lot of letters goes inside another (taking inside).
'rump' becomes 'rest' (I can't explain this - if you can you should give a lot more credence to this answer).
'lewd' is an anagram of 'wled'.
'wled' placed around 'rest' is 'WRESTLED'.
Can you help me to learn more?
(Other definitions for wrestled that I've seen before include "Fought" , "Struggled" .)
