To tear round and round? (6)
I believe the answer is:
rotate
'round?' is the definition.
(thesaurus)
'to tear round' is the wordplay.
'round' indicates an anagram.
'to'+'tear'='totear'
'totear' is an anagram of 'ROTATE'.
'and' acts as a link.
(Other definitions for rotate that I've seen before include "wheel" , "Turn round" , "Go around" , "Gyrate" , "'Er, to a T? (anag)" .)
