Artist has plant to gorge (6)
I believe the answer is:
ravine
'to gorge' is the definition.
(I've seen this before)
'artist has plant' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'has plant' becomes 'vine' (I can't justify this - if you can you should believe this answer much more).
'ra'+'vine'='RAVINE'
Can you help me to learn more?
(Other definitions for ravine that I've seen before include "Narrow, steep-sided valley" , "Deep narrow valley" , "'Deep, steep valley (6)'" , "Steep-sided gorge" , "Deep narrow gorge between mountains" .)
