Drops on the ground (3)

I believe the answer is:

dew

'drops on the ground?' 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 "Night fall of moisture" , "Condensation at beginning or end of day" , "Moisture on grass" , "Night-time condensation" , "Moisture on ground" .)

I've seen this clue in the USA Today, the New York Times, the Newsday, the Universal and the Sydney Morning Herald.
