A novice getting better all round at sport (7)
I believe the answer is:
curling
'sport' is the definition.
(curling is a sport)
'a novice getting better all round' is the wordplay.
I cannot quite understand how this works, but
'novice' could be 'l' (as in a learner driver with L-plates on their car) and 'l' is located in the answer.
'round' could be 'ring' (synonyms) and 'ring' is found in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
'at' is the link.
Can you help me to learn more?
(Other definitions for curling that I've seen before include "Not a straightforward" , "Doing the twist" , "Sport played on ice" , "providing treatment for shock?" , "Game played on ice" .)
