What does chesnut mean?
"Chesnut" is a historical spelling variant of "chestnut," the English word for both the glossy brown edible nut of trees in the genus Castanea and the trees themselves. As a colour term it describes a warm reddish-brown, applied to hair, horses, leather, and other surfaces, and as a horse classification a chesnut is an animal of that coat colour. Roasted chestnuts have long been associated with winter streets and festive cooking, giving the word strong seasonal and nostalgic connotations. Although the spelling with the medial 't' is now firmly established in dictionaries, the 't'-less "chesnut" appeared widely in earlier English texts and persists in some surnames and place names. Today any use of "chesnut" is best treated as archaic or simply incorrect, and readers encountering it should understand it as referring to everything the standard spelling covers.
noun"Chesnut" is a historical or nonstandard spelling variant of "chestnut," denoting the edible nut of the chestnut tree (genus Castanea), the tree itself, or a reddish-brown color.
- An edible nut from trees of the genus Castanea, with a hard shiny brown shell.
- A tree bearing such nuts.
- A dark reddish-brown colour.
- (Of hair or a horse's coat) of a reddish-brown colour; a horse of that colour.
"She roasted the chesnuts over an open fire on the first cold night of autumn."
"The street vendors sold paper cones of hot roasted chesnuts to passers-by."
"He rode a fine chesnut mare across the fields."
Like its standard form, the plural is regular: add -s. Modern writing uses "chestnuts."
"The market stalls were piled high with fresh chesnuts in October."
Before spelling was standardized in dictionaries, writers couldn't agree on the 't' — so if you've ever typed 'chesnut' by accident, you're in the company of centuries of English writers who did it on purpose.

Etymology of chesnut
The word entered Middle English from Old French "chastaigne" (modern French "châtaigne"), borrowed from Latin "castanea," which itself came from Greek "kastanon," likely ultimately from a language of Asia Minor where the tree was cultivated. The medieval spellings varied considerably — including forms like "chasten," "chesten," and "chesteyn" — because English speakers reinterpreted the ending through association with "nut." The spelling "chesnut," without the second 't,' was one of several accepted variants until lexicographic standardization in the eighteenth and nineteenth centuries fixed "chestnut" as the sole correct form.
How chesnut is actually used
"Chesnut" is now regarded as a misspelling; modern writing should use "chestnut." The older spelling appears frequently in literature printed before the nineteenth century and survives in some proper nouns and place names. In British English the plural of the standard form is sometimes heard as "chestnuts roast" in the carol line, but the noun plural is simply "chestnuts."
