Artist has returned with article from desert (7)
I believe the answer is:
saharan
'from desert' is the definition.
(I've seen this before)
'artist has returned with article' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'returned' shows that the letters should be reversed in order.
'with' says to put letters next to each other.
'article' becomes 'an' (indefinite article).
'ra'+'has'='rahas'
'rahas' reversed gives 'sahar'.
'sahar'+'an'='SAHARAN'
(Other definitions for saharan that I've seen before include "Baking" , "Deserter" , "Relating to the North African desert" .)
