He turns out to be the winner by one point (7)
I believe the answer is:
evictor
'he turns out' is the definition.
(I've seen this before)
'to be the winner by one point' is the wordplay.
I cannot quite understand how this works, but
'to' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'point' could be 'e' (compass point) and 'e' is present in the answer.
The remaining letters 'vcr' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for evictor that I've seen before include "One turning out" , "Nightclub bouncer?" , "who puts an end to occupation?" , "One turns out" , "One who boots out" .)
