Best digs around so they say (5)
I believe the answer is:
prize
'best' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for prize that I've seen before include "See 16" , "Reward for win" , "See 24 Down" , "Booty" , "Reward won in competition" .)
