Artist to take the air? (5)
I believe the answer is:
degas
This clue is a double definition.
'artist' is the first definition.
(I've seen this in other clues)
'take the air?' is the second definition.
(de-gas, to remove gas)
'to' is the link.
(Other definitions for degas that I've seen before include "Edgar -, c. Nineteen-twenty Fr. painter" , "Edgar -, French impressionist" , "Edgar ---, Fr. impressionist" , "French impressionist painter, d. 1917" , "Edgar --, French artist" .)
