Like dunes (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
sandy
'like dunes' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sandy that I've seen before include "Like many beaches" , "Reddish (hair); like a good beach" , "gritty" , "Like a beach perhaps" , "Light yellowish brown" .)
