Damp, round figure seen in the haze (5)
I believe the answer is:
moist
'damp' is the definition.
(I know that damp can be written as moist)
'round figure seen in the haze' is the wordplay.
'round figure' becomes 'o'.
'seen in' is an insertion indicator.
'the haze' becomes 'mist' (I've seen this in another clue).
'o' placed into 'mist' is 'MOIST'.
(Other definitions for moist that I've seen before include "sloppy" , "Slightly wet, damp" , "bit wet" , "Damp, humid" , "Affected by tears, perhaps" .)
