Point from newspaperman is certainly a runner (8)
I believe the answer is:
sprinter
'runner' is the definition.
(sprinter is a kind of runner)
'point from newspaperman is certainly a' is the wordplay.
I cannot quite understand how this works, but
'point' could be 's' (S is an example) and 's' is located in the answer.
'from' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sprinter that I've seen before include "He runs as fast as he can over short distance" , "one promising a fast run?" , "speedy runner" , "Person in short race" , "Bolt, say" .)
