Nursery crop with holes spreading (9)
I believe the answer is:
preschool
'nursery' is the definition.
(I've seen this in another clue)
'crop with holes spreading' is the wordplay.
'with' is a charade indicator (letters next to each other).
'spreading' indicates anagramming the letters.
'crop' put after 'holes' is 'holescrop'.
'holescrop' with letters rearranged gives 'PRESCHOOL'.
(Other definitions for preschool that I've seen before include "Kindergarten" , "early years" , "provided for kiddies?" , "before education" .)
