French artist shortly to enclose quotation for composite picture (7)
I believe the answer is:
montage
'composite picture' is the definition.
(I've seen this before)
'french artist shortly to enclose quotation for' is the wordplay.
'french artist' becomes 'monet' (I've seen this in another clue).
'shortly' means to remove the last letter.
'to enclose' is an insertion indicator.
'quotation for' becomes 'tag' (I can't explain this - if you can you should believe this answer much more).
'monet' with its last letter taken off is 'mone'.
'mone' placed around 'tag' is 'MONTAGE'.
Can you help me to learn more?
(Other definitions for montage that I've seen before include "Picture comprising disparate elements" , "set of images" , "Picture assembled from separate sections" , "Composite picture" , "Artwork - not a gem (anag)" .)
