Issue about a new projection (6)
I believe the answer is:
canopy
'projection' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'issue about a new' is the wordplay.
'issue' becomes 'copy' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' is an insertion indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'a'+'n'='an'
'copy' placed around 'an' is 'CANOPY'.
Can you help me to learn more?
(Other definitions for canopy that I've seen before include "Hanging cover over bed, shopfront, etc" , "Roof-like shelter" , "Overhead covering, on bed or throne say" , "Hanging cover forming shelter over bed or throne" , "Cockpit cover" .)
