Figure to enjoy the thing (5)
I believe the answer is:
digit
'figure' is the definition.
(numerical figure)
'enjoy the thing' is the wordplay.
'enjoy' becomes 'dig' (to dig can mean to appreciate or 'get').
'the thing' becomes 'it'.
'dig'+'it'='DIGIT'
'to' is the link.
(Other definitions for digit that I've seen before include "Finger, thumb or toe" , "using 0 or 1 for example" , "Single number" , "Single numeral" , "One's on hand" .)
