Chestnut
The
chestnut gathering is a class (Castanea) of eight or nine types of deciduous
trees and bushes in the beech family Fagaceae, local to calm districts of the
Northern Hemisphere.
The
name likewise alludes to the consumable nuts they create
The
name "chestnut" is gotten from a before English term "chesten
nut", which dives from the Old French word chastain (Modern French,
châtaigne).[11]
The
trees' names are for all intents and purposes indistinguishable in all the most
old dialects of Central Europe: in Breton kistinen for the tree, and kistin for
its natural product, in Welsh castan-wydden and sataen, in Dutch kastanje for
both the tree and its organic product, in Albanian gështenjë, in Hungarian
gesztenye, and numerous others near the French châtaigne and to the Latin name
decided for the family, Castanea.[12]
The
name Castanea is presumably gotten from the old name for the sweet chestnut,
either in Latin[13] or in Ancient Greek. Another conceivable wellspring of the
name is the town of Kastania in Thessaly, Greece;[5] more likely, however, is
that the town took its name from the most widely recognized tree developing
around it.[12] In the Mediterranean atmosphere zone, chestnut trees are rarer
in Greece in light of the fact that the pasty soil is not helpful for the
tree's development. Kastania is situated on one of the generally couple of
sedimentary or siliceous outcrops. They develop so inexhaustibly there, their
nearness would have decided the spot's name.[14] Still others take the name as
originating from the Greek name of Sardis glans (Sardis oak seed) – Sardis
being the capital of Lydia, Asia Minor, from where the organic product had
spread.[15]
The
name is refered to twice in the King James Version of the Bible. In one
occasion, Jacob puts peeled twigs in the water troughs to advance solid
posterity of his livestock.[16] Although it might demonstrate another tree, it
shows the organic product was a nearby staple sustenance in the mid seventeenth
century.[12]
These
equivalent words are or have been being used: Fagus castanea (utilized by
Linnaeus as a part of first release of Species Plantarum, 1753),[17] Sardian
nut, Jupiter's nut, husked nut, and Spanish chestnut (U.S.)
