In the altogether natural condition (5)
I believe the answer is:
naked
'in the altogether' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for naked that I've seen before include "Without clothes" , "Bare" , "Au naturel" , "Without protection" , "Defenceless" .)
