Certain sheep in Rome butchered (6)
I believe the answer is:
merino
'certain sheep' is the definition.
'Merino' can be an answer for 'sheep' (breed of sheep). I'm not certain of the 'certain' bit.
'in rome butchered' is the wordplay.
'butchered' indicates an anagram (I've seen this in other clues).
'in'+'rome'='inrome'
'inrome' anagrammed gives 'MERINO'.
Can you help me to learn more?
(Other definitions for merino that I've seen before include "Breed of sheep with fine wool" , "The sheep provides fine wool" , "Fine soft woolen yarn" , "Australian sheep" , "Long-haired sheep" .)
