Like some nervous palms (6)
I believe the answer is:
sweaty
'like some nervous palms' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sweaty that I've seen before include "Hot and perspiring" , "Given to perspiring, in moist state" , "Damp with perspiration" , "Covered in perspiration" , "Showing effects of fever" .)
