Recipient of corn and French grain (6)
I believe the answer is:
millet
'grain' is the definition.
(I know that millet is a type of grain)
'recipient of corn and french' is the wordplay.
'recipient of corn' becomes 'mill' (a mill might grind corn).
'and french' becomes 'et' ('and' in French).
'mill'+'et'='MILLET'
(Other definitions for millet that I've seen before include "Seed from cereal grasses - French painter, d.1875" , "Cereal - French painter, d. 1875" , "sort of grass" , "Cereal; French artist" , "Food grain" .)
