Morphology

sweet + chestnut

The core meaning comes directly from 'chestnut' which already denotes a reddish-brown colour, and 'sweet' simply modifies that noun without introducing an unpredictable idiomatic sense. A B1 learner who knows both words can readily infer this denotes a shade related to the chestnut nut/timber (a medium–dark reddish‑brown), a compositional pattern common across languages.

Etymology

The noun sweet chestnut comes from people eating and roasting the tree's tasty nuts. The name joins sweet, because the nuts taste good, and chestnut, meaning the nut and the tree, so the phrase now means the tree that gives edible nuts.
