Target for livestock (4)
I believe the answer is:
bull
This could be a double definition.
'target' is the first definition.
(centre of a target)
'livestock' is the second definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'for' is the link.
Can you help me to learn more?
(Other definitions for bull that I've seen before include "Sign" , "Official papal edict" , "motion is > nonsense" , "Animal on target?" , "Male bovine - target's centre" .)
