Lawn condensation (3)
I believe the answer is:
dew
'lawn condensation' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dew that I've seen before include "Early morning condensation" , "It forms on cool surfaces at night" , "Morning or evening condensation" , "Night-time moisture" , "Condensation at beginning or end of day" .)
