Perhaps Harvey Nicks delivery expected – primarily with unopened flat pack (10,5)
I believe the answer is:
department store
'primarily with unopened flat pack' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'perhaps harvey nicks delivery expected' is the wordplay.
I cannot really see how this works, but
'expected' could be 'par' (as in 'par for the course') and 'par' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for department store that I've seen before include "shopping centre" , "place on the high street" , "Big shop" , "large shop" , "Building" .)
