It seems odd, releasing end of rope from show bull (7)
I believe the answer is:
paradox
'it seems odd releasing end of rope' is the definition.
The definition suggests a singular noun which matches the answer.
'show bull' is the wordplay.
'show' becomes 'parad' (I am not sure about this - if you are sure you should believe this answer much more).
'bull' becomes 'ox'.
'parad'+'ox'='PARADOX'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for paradox that I've seen before include "self-contradiction" , "[Still without being stll] ?" , "An apparent absurdity" , "Statement seeming to be self-contradictory" , "A seemingly contradictory statement" .)
