Uneven, rough (5)
I believe the answer is:
bumpy
This clue is a double definition.
'uneven' is the first definition.
(I've seen this before)
'rough' is the second definition.
(I know that rough can be written as bumpy)
(Other definitions for bumpy that I've seen before include "Rough - turbulent" , "(Of flight) rough" , "affected by air pockets" , "Not even" , "My pub (anag.)" .)
