Like flying birds circling new canvas sunshade (6)
I believe the answer is:
awning
'sunshade' is the definition.
(synonyms)
'like flying birds circling new canvas' is the wordplay.
I cannot really understand how this works, but
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is located in the answer.
'flying' could be 'awing' (rare adverb, sometimes spelled a-wing) and 'awing' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for awning that I've seen before include "Shop's sun shade" , "Cover over shop-front" , "Canopy for shelter from rain or sun" , "Shelter over a window" , "Sunshade" .)
