It's rather more pleasant in an ice rink (5)
I believe the answer is:
nicer
'it's rather more pleasant' is the definition.
I can't tell whether this definition defines the answer.
'in an ice rink' is the wordplay.
'in' says the answer is hidden in the clue.
'NICER' is hidden in the letters of 'an ice rink'.
Can you help me to learn more?
(Other definitions for nicer that I've seen before include "harder to please" , "More pleasant or courteous" , "Pleasanter" , "more accurate" , "better" .)
