noun / adjective
chestnut
CHES-nut/ˈtʃesnʌt/
A deciduous tree bearing glossy brown edible nuts.
The chestnut bears glossy nuts inside spiny burrs.

Etymology
The first component already named the chestnut or its tree, so adding “nut” repeated information rather than supplying a new meaning. The compound explicitly identifies the edible nut.
In context
To roast the chestnuts, simply score an X into the chestnut um a little deeper than the skin.
