Style of robbery through a broken display window
I believe the answer is:
smash-and-grab
'style of robbery through a broken display window' is the definition.
(I've seen this before)
'a broken display window' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for smash-and-grab that I've seen before include "Type of shop window robbery" , "Break-in (through a shop window)" , "Sudden robbery" , "Type of raid" , "Descriptive of a robbery" .)
