Harry loves to do crosswords perhaps (5)
I believe the answer is:
solve
'do crosswords perhaps' is the definition.
I can't judge whether this defines the answer.
'harry loves' is the wordplay.
'harry' indicates anagramming the letters (harry can mean to attack or spoil).
'loves' anagrammed gives 'SOLVE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for solve that I've seen before include "Find the answer to a mystery" , "Complete crossword" , "Figure out the answer" , "Find an answer to (a problem)" , "Find the answer to a puzzle" .)
