Scenery from Christmas month, centrepiece for stores (5)
I believe the answer is:
decor
'scenery' is the definition.
(I've seen this in another clue)
'christmas month centrepiece for stores' is the wordplay.
'christmas' becomes 'dec' (Dec is short for December, the Christmas period).
'month' becomes 'Nov' (abbreviation for November).
'centrepiece' means to look at the middle letters (the letter at the centre).
'for stores' becomes 'r' (I can't justify this - if you can you should give a lot more credence to this answer).
The centre of 'nov' is 'o'.
'dec'+'o'+'r'='DECOR'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for decor that I've seen before include "Scheme of interior furnishings" , "Style of furnishings, drapes etc used in a room" , "(Room) design" , "Credo (anag.)" , "Colour-scheme etc of a room" .)
