Could you use them for mutton? (4)
I believe the answer is:
ewes
'could you use' is the definition.
I can't tell whether this definition defines the answer.
'them for mutton?' is the wordplay.
'them' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'for' says to put letters next to each other (I've seen this in other clues).
'mutton?' becomes 'ewe'.
's' put after 'ewe' is 'EWES'.
Can you help me to learn more?
(Other definitions for ewes that I've seen before include "wool producers" , "Females in the flock" , "Sheep (females)" , "farm animals" , "Female sheep" .)
