Ollie's comic partner (4)
I believe the answer is:
stan
'ollie's comic partner' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stan that I've seen before include "Laurel perhaps" , "Laurel and Hardy, . . . . and Ollie" , "- Laurel, Hardy's partner" , "guy" , "Ollie's partner" .)
