Primate to leave artist sick to stomach (7)
I believe the answer is:
gorilla
'primate' is the definition.
(I know that gorilla is a type of great ape)
'leave artist sick to stomach' is the wordplay.
I cannot quite see how this works, but
'leave' could be 'go' (to go is to depart or leave) and 'go' is found in the answer.
'sick' could be 'ill' (similar in meaning) and 'ill' is found in the answer.
'artist' could be 'ra' (Royal Academician, member of Royal Academy of Arts) and 'ra' is present in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for gorilla that I've seen before include "Heavy" , "thug" , "A large powerful African ape" , "Chest-beating primate" , "big mammal" .)
