Save artist given partially digested food, a fish (9)
I believe the answer is:
barracuda
'fish' is the definition.
(barracuda is a kind of fish)
'save artist given partially digested food a' is the wordplay.
'save' becomes 'bar' (I've seen this before).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'given partially digested food' becomes 'cud' (I can't explain this - if you can you should give a lot more credence to this answer).
'bar'+'ra'+'cud'+'a'='BARRACUDA'
Can you help me to learn more?
(Other definitions for barracuda that I've seen before include "big fish" , "Voracious marine fish" , "Marine attacker" , "Vicious swimmer" , "Large predatory sea fish" .)
