Etymology and names

The name plum derived from Old English plume "plum, plum tree", borrowed from Germanic or Middle Dutch, derived from Latin prūnum and ultimately from Ancient Greek προῦμνον proumnon, itself believed to be a loanword from an unknown language of Asia Minor. In the late 18th century, the word plum was used to indicate "something sweet or agreeable", probably in reference to tasty fruit pieces in desserts, as in the word sugar-plum.
