Not as moist (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
drier
'not as moist' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for drier that I've seen before include "Flatter" , "Less moist" , "Airer" , "More arid" , "Appliance to remove moisture" .)
