Chestnut
/ˈtʃes.nʌt/noun
A hard-shelled edible nut from the chestnut tree, or the tree itself.
Did you know?English got *chestnut* through Old French from a Latin word for the nut, and that Latin form was ultimately tied to an ancient Greek tree-name—proof that even ordinary food words can carry the memory of Mediterranean trade routes.
