Females in the field manipulate sounds (4)
I believe the answer is:
ewes
'females in the field' is the definition.
The answer and definition can be both animals as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'manipulate sounds' is the wordplay.
'manipulate' becomes 'use' (using is a kind of manipulating).
'sounds' shows a homophone (sound like).
'use' is a homophone of 'EWES'.
Can you help me to learn more?
(Other definitions for ewes that I've seen before include "wool producers" , "Females in the flock" , "Adult sheep" , "farm animals" , "members of flock" .)
