Fine god’s vegetable (4)
I believe the answer is:
okra
'vegetable' is the definition.
(okra is a kind of vegetable)
'fine god's' is the wordplay.
'fine' becomes 'ok' (synonyms).
'god' becomes 'Ra' (Egyptian god).
'ok'+'ra'='OKRA'
(Other definitions for okra that I've seen before include "Bhindi, gumbo or ladies' fingers" , "Long green tropical vegetable" , "vegetable dish" , "old ladies' fingers" , "Tropical plant with edible pods" .)
