To tear madly round and round! (6)
I believe the answer is:
rotate
'round' is the definition.
(thesaurus)
'to tear madly' is the wordplay.
'madly' indicates an anagram.
'to'+'tear'='totear'
'totear' anagrammed gives 'ROTATE'.
'round and' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rotate that I've seen before include "Turn around an axle, swivel" , "Make to spin around" , "Go round and round" , "Turn round" , "Revolve" .)
