Think shop needs rebuke (10)
I believe the answer is:
deliberate
'think' is the definition.
(thesaurus)
'shop needs rebuke' is the wordplay.
'shop' becomes 'deli' (deli is a kind of shop).
'needs' is a charade indicator (letters next to each other).
'rebuke' becomes 'berate' ('berate' can be a synonym of 'rebuke').
'deli'+'berate'='DELIBERATE'
(Other definitions for deliberate that I've seen before include "Calculated - think carefully" , "Consider carefully" , "Ponder" , "Done intentionally" , "Consider - intentional" .)
