"Châtaigne: femelle du marron" -- Gustave Flaubert, Dictionnaire des Idées Reçues
An unfinished work that Gustave Flaubert began in 1850 and continued til the end of his life in 1880 was a collection of sometimes silly French aphorisms, Dictionniare des Idées Reçus. A must.
Know that in France when the edible sweet chestnut, la chataigne, is transformed into culinary delights, it is most often called "un marron." The common, non-edible horse chestnut, is also called un marron.
une idée reçue: a preconceived notion
cherchez la femme: literally, look for the woman; the idea being that if a man's behavior is out of character or strange it is because he is either trying to hide an extra-marital affair, or trying to impress a woman. The term was coined by Alexandre Dumas.
