Unbroken flow damaged hunter's target (8)
I believe the answer is:
wildfowl
'hunter's target' is the definition.
The definition suggests a singular noun which matches the answer.
'unbroken flow damaged' is the wordplay.
'unbroken' becomes 'wild' (similar in meaning).
'damaged' indicates an anagram.
'flow' with letters rearranged gives 'fowl'.
'wild'+'fowl'='WILDFOWL'
Can you help me to learn more?
(Other definitions for wildfowl that I've seen before include "Game birds" , "Ducks etc" , "Grouse and pheasant, for instance" , "sport for guns?" .)
