Origin & History of “prune”

English has two distinct words prune. The older, ‘dried plum’ (14th c.), is ultimately the same word as plum, and indeed in the 16th and 17th century was often used for ‘plum’. It comes via Old French prune from vulgar Latin *prūna, which also gave English (through Germanic) plum. Prune ‘cut off unneeded parts’ (15th c.) denotes etymologically ‘cut in a rounded shape in front’. It comes via Old French proignier from Vulgar Latin *prōrotundiāre, a compound verb formed from the Latin prefix prō- ‘in front’ and rotundus ‘round’ (source of English rotund and round).
