One also raised not to work? (3)
I believe the answer is:
dud
'one' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dud that I've seen before include "Palindrome for a flop" , "Not functioning" , "Defective" , "Explosive not detonating" , "Bullet that fails to fire" .)
