Dried fruit is placed in water (6)
I believe the answer is:
raisin
'dried fruit' is the definition.
(raisin is a kind of dried fruit)
'is placed in water' is the wordplay.
'placed in' is an insertion indicator (I've seen this in other clues).
'water' becomes 'rain' (rain is a kind of water).
'is' going into 'rain' is 'RAISIN'.
(Other definitions for raisin that I've seen before include "Cultivating" , "Fruit for the Christmas cake" , "Large dried grape" , "Dried red grape" , "sultana, say" .)
