Liking a bit of a quarrel? I should know! (6)
I believe the answer is:
relish
'liking' is the definition.
(thesaurus)
'a bit of a quarrel? i should know' is the wordplay.
'a bit of' says the answer is hidden in the clue.
'RELISH' is hidden in the letters of 'quarrel i should know'.
(Other definitions for relish that I've seen before include "Salsa-like sauce" , "appreciate" , "Piquant sauce or pickle" , "Spicy or savoury condiment" , "Salsa, chutney etc" .)
