Drops of water (5)
I believe this is a double definition.
'drops' is the first definition.
('fall' can be a synonym of 'drop')
'water' is the second definition.
(I know that falls is a type of water)
'of' is the link.
(Other definitions for falls that I've seen before include "American seasons" , "Plummets" , "North Country force" , "Drops" , "Victoria or Niagara, for example" .)
(Other definitions for dew that I've seen before include "The damp of early morning" , "'The foggy, foggy - - ' (song)" , "Early morning moisture" , "Early morning condensation" , "Overnight condensation" .)
