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 anagramming the letters.
'to'+'tear'='totear'
'totear' is an anagram of 'ROTATE'.
'round and' is the link.
This may not be right. Some or all of it may be part of 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" .)
