Rough journey for auditors (6)
I believe the answer is:
coarse
'rough' is the definition.
(associated in meaning)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for coarse that I've seen before include "needing refinement" , "Unrefined; rough" , "lacking in taste" , "Rought or crude" , "Large-grained or rough to the touch" .)
