Sprinkle items on ground (7)
I believe the answer is:
moisten
'sprinkle' is the definition.
(I know that moisten is a more specific form of the action sprinkle)
'items on ground' is the wordplay.
'ground' indicates an anagram ('grind' the letters into a new form).
'items'+'on'='itemson'
'itemson' anagrammed gives 'MOISTEN'.
(Other definitions for moisten that I've seen before include "Add water - dampen" , "Make damp or slightly wet" , "contrary to sixteen down [DEHYDRATE]!" , "It's on me (anag)" , "Make damp, say lips with tongue" .)
