Colleague, associate (8)
I believe the answer is:
confrere
I believe this is a double definition.
'colleague' is the first definition.
(I know that colleague can be written as confrere)
'associate' is the second definition.
(I know that confrere is a type of associate)
(Other definitions for confrere that I've seen before include "Enforcer as professional colleague or associate" , "Fellow member" , "colleague from France" .)
