Slightly damp or wet (5)
I believe the answer is:
moist
I believe this is a double definition.
'slightly damp' is the first definition.
(I've seen this in another clue)
'wet' is the second definition.
(I know that wet can be written as moist)
(Other definitions for moist that I've seen before include "Damp or clammy" , "sloppy" , "Affected by tears, perhaps" , "Slightly wet, damp" , "bit wet" .)
