A bare description is required (5)
I believe the answer is:
naked
'a bare' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for naked that I've seen before include "Undressed" , "Without protection" , "In the altogether" , "Blatant" , "In one's birthday suit" .)
