Fewer round livestock (3)
I believe the answer is:
ewe
'round livestock' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'fewer' is the wordplay.
'EWE' is hidden within the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for ewe that I've seen before include "Language" , "Directions" , "Female ovine" , "She'll provide material to knit" , "Palindrome for a female sheep" .)
