Stand, nude and shivering, before again (6)
I believe the answer is:
endure
'stand' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for endure that I've seen before include "Remain in existence; suffer" , "Last or bear with courage" , "Last or suffer patiently" , "Undergo a tough time" , "'Last, bear (6)'" .)
