Due condensation (3)
I believe the answer is:
dew
This might be a double definition.
'due' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'condensation' is the second definition.
(dew is a kind of condensation)
(Other definitions for dew that I've seen before include "'The foggy, foggy - - ' (song)" , "Wed in morning moisture" , "Moisture condensed at night" , "Moisture on ground" , "The damp of early morning" .)
