Go round arranging a treat out of love (6)
I believe the answer is:
rotate
'go round' is the definition.
(thesaurus)
'arranging a treat out of love' is the wordplay.
'arranging' indicates anagramming the letters.
'out of' indicates putting letters inside.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'treat' is an anagram of 'rtate'.
'rtate' going around 'o' is 'ROTATE'.
(Other definitions for rotate that I've seen before include "Spin round" , "Pirouette" , "wheel" , "Move round centre" , "Whisk round" .)
