Barker unsteady on his feet? (7)
I believe the answer is:
lurcher
This clue might be a double definition.
'barker' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'unsteady on his feet?' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
Can you help me to learn more?
(Other definitions for lurcher that I've seen before include "Crossbred hunting dog" , "one unsteady on his feet" , "Crossbred dog similar to a greyhound" , "canine cross?" , "moving suddenly and unsteadily?" .)
