Some rhetoric! Editor's frozen (4)
I believe the answer is:
iced
'frozen' is the definition.
(I've seen this in another clue)
'some rhetoric editor's' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ICED' is hidden in the letters of 'rhetoric editors'.
(Other definitions for iced that I've seen before include "Covered with flavoured sugar topping" , "Decorated; killed" , "Finished off cake" , "Decorated (a cake)" , "Decorated with frosting" .)
