Naked as a grizzly, I say (4)
I believe the answer is:
bare
'naked' is the definition.
(without clothing)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bare that I've seen before include "Mere" , "State of deciduous tree in winter" , "Denuded" , "Uncovered - unfurnished - unadorned" , "Naked or empty" .)
