Greatly enjoy being skilful and winning (8)
I believe the answer is:
loveable
'winning' is the definition.
Both the definition and answer are adjectives.
Maybe you can see an association between them that I can't see?
'greatly enjoy being skilful' is the wordplay.
'greatly enjoy' becomes 'love' (synonyms. I am not sure about the 'greatly' bit.).
'being skilful' becomes 'able' (I've seen this before).
'love'+'able'='LOVEABLE'
'and' acts as a link.
Can you help me to learn more?
(Another definition for loveable that I've seen is " Attractive, endearing".)
