Some quarrel is hindering enjoyment (6)
I believe the answer is:
relish
'enjoyment' is the definition.
(relish is a kind of enjoyment)
'some quarrel is hindering' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'RELISH' can be found hidden inside 'quarrel is hindering'.
(Other definitions for relish that I've seen before include "Savour; an appetiser" , "Sauce; zest" , "Piquant sauce or pickle" , "Great enjoyment; sauce" , "Much enjoy" .)
