Part of building resembling a shop? (6)
I believe the answer is:
storey
'part of building' is the definition.
('storey' is part of 'building')
'a shop?' is the wordplay.
I cannot really understand how this works, but
'shop?' could be 'store' ('store' can be a synonym of 'shop') and 'store' is present in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'resembling' acts as a link.
(Other definitions for storey that I've seen before include "Oyster (anag) -- level" , "Floor or level in a building" , "part of the building" , "rooms on one level" , "Tier of a building" .)
