Spike may be mistaken getting power for women (5)
I believe the answer is:
prong
'spike' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for prong that I've seen before include "Spur; projecting part" , "Point of a fork" , "Pointed end of fork" , "Tooth" , "branch" .)
