Etymology: Juglandaceae is the botanical family name for the walnut family, and its name comes straight from the genus "Juglans," the Latin word for the walnut tree. The Latin "juglans" is usually explained as a contraction of "Jovis glans," meaning "Jupiter's acorn" or "nut of Jove," a name that reflects how the Romans regarded the walnut as a prestigious nut. That etymology is widely cited, though the exact details of how the compression happened are not fully certain. The "-aceae" ending is a standard suffix used across botany to mark a family name, taken from the Latin plural ending applied to the type genus. Botanists settled on this naming pattern in the 19th century, so the word as a whole is a modern scientific coinage built on an ancient Latin root. Its English-facing counterpart, "walnut," is different: it comes from Old English "wealhhnutu," meaning "foreign nut," because the nut was introduced to Britain by the Romans and the Anglo-Saxons associated it with the Welsh-speaking "Wealh" peoples.
