Impotent, imotent? (9)
I believe the answer is:
powerless
'impotent' is the definition.
(associated in meaning)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for powerless that I've seen before include "Lacking ability" , "hamstrung" , "Weak, impotent" , "Without ability" .)
