Liking being mean, twisting the tail (7)
I believe the answer is:
partial
'liking being mean twisting the tail' is the definition.
I can't tell whether this definition defines the answer.
'mean twisting the tail' is the wordplay.
'mean' becomes 'par' (average score on a golf course).
'twisting' indicates anagramming the letters.
'tail' with letters rearranged gives 'tial'.
'par'+'tial'='PARTIAL'
Can you help me to learn more?
(Other definitions for partial that I've seen before include "Not complete or total, maybe an eclipse" , "One-sided" , "Not complete, or with strong liking for" , "Favouring one over another" , "Fragmentary" .)
