In Italian, marron is not a standard word, but you might come across it in some regional dialects. The correct Italian term is marrone, which has two main meanings: it refers to both the color brown and a type of chestnut.
When used to describe the color, marrone refers to anything brown, such as clothing, objects, or even hair.
Ho comprato una giacca marrone. – I bought a brown jacket.
Il tavolo è di legno marrone. – The table is made of brown wood.
Marrone also refers to a specific type of chestnut, larger and often considered of higher quality. These chestnuts are commonly used in culinary dishes or turned into marron glacé, a popular candied chestnut delicacy, especially during the holiday season.
In autunno, raccolgono i marroni nei boschi. – In autumn, they collect chestnuts in the woods.
I marron glacé sono dolci tipici natalizi. – Marron glacé are traditional Christmas sweets.
In some Italian dialects, marron may still be used to refer to chestnuts, but in standard Italian, marrone is the correct and widely recognized term for both the color and the chestnut.
