View taking in shop window (9)
I believe the answer is:
sidelight
'window' is the definition.
(type of window)
'view taking in shop' is the wordplay.
'view' becomes 'sight' (synonyms).
'taking in' means one lot of letters goes inside another.
'shop' becomes 'deli' (deli is a kind of shop).
'sight' going around 'deli' is 'SIDELIGHT'.
(Other definitions for sidelight that I've seen before include "thin illumination" , "Car part" , "Additional or incidental information" , "Window" , "Small illumination (on car)" .)
