A bit wet (5)
I believe the answer is:
moist
'bit wet' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for moist that I've seen before include "Slightly wet, damp" , "lubricated" , "sloppy" , "Dampish" , "Affected by tears, perhaps" .)
