Mislead new candidate (9)
I believe the answer is:
contender
'candidate' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for contender that I've seen before include "Trend once (anag.)" , "Candidate" , "One striving" , "One who strives" , "Struggler in rivalry" .)
