Enjoy its numbers (6)
I believe the answer is:
digits
'numbers' is the definition.
(digit is a kind of number)
'enjoy its' is the wordplay.
'enjoy' becomes 'dig' (to dig can mean to appreciate or 'get').
'dig'+'its'='DIGITS'
(Other definitions for digits that I've seen before include "Numbers 0 to 9" , "One to nine" , "Fingers, toes and numbers" .)
