Fewer around livestock (3)
I believe the answer is:
ewe
'livestock' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'fewer around' is the wordplay.
'around' says the answer is hidden in the clue.
'EWE' is hidden in the letters of 'fewer'.
Can you help me to learn more?
(Other definitions for ewe that I've seen before include "Female ovine" , "Lamb's dam" , "Lamb's mother" , "Partner to ram" , "Female bleater" .)
