Wildly loves crack (5)
I believe the answer is:
solve
'crack' is the definition.
(I've seen this before)
'wildly loves' is the wordplay.
'wildly' is an anagram indicator.
'loves' anagrammed gives 'SOLVE'.
(Other definitions for solve that I've seen before include "Get the answers" , "Find the answer to a puzzle" , "Find the answer to this clue, for instance" , "Crack clues" , "Settle" .)
