Child, perhaps, of La Rochefoucauld (4)
I believe the answer is:
chef
'child' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'of la rochefoucauld' is the wordplay.
'of' says the answer is hidden in the clue.
'CHEF' is hidden in the letters of 'la rochefoucauld'.
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for chef that I've seen before include "Principal cook" , "Head cook in a restaurant" , "Saucier" , "Chief male cook in restaurant" , "Key kitchen worker" .)
