Puzzled, need hint finally (2,3,3)
I believe the answer is:
in the end
'finally' is the definition.
(synonyms)
'puzzled need hint' is the wordplay.
'puzzled' is an anagram indicator.
'need'+'hint'='needhint'
'needhint' anagrammed gives 'IN THE END'.
(Other definitions for in the end that I've seen before include "Then Enid came at last" , "Ultimately" , "Eventually" , "At long last" , "Finally" .)
