Creche in North Surrey reorganised (7)
I believe the answer is:
nursery
'creche' is the definition.
(I've seen this before)
'north surrey reorganised' is the wordplay.
'north' becomes 'N' (synonyms).
'reorganised' indicates anagramming the letters.
'surrey' with letters rearranged gives 'ursery'.
'n'+'ursery'='NURSERY'
'in' acts as a link.
(Other definitions for nursery that I've seen before include "Growing environment for plants or children" , "and 29: Novice's ski run" , "Place for tending young children, or plants" , "Place where young plants are grown" , "Garden centre" .)
