Map or an adaptation with a very wide view (8)
I believe the answer is:
panorama
'wide view' is the definition.
(I've seen this in another clue)
'map or an adaptation with a' is the wordplay.
'adaptation with' indicates an anagram.
'map'+'or'+'an'='maporan'
'maporan' with its letters anagrammed with 'a' gives 'PANORAMA'.
'very' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for panorama that I've seen before include "Wide view of surrounding area" , "Picture" , "Am on a par (anag)" , "A view that's wide" , "Overall view" .)
