The word parsnip was borrowed into Middle English in the 14th century as a modification of the Old French word pasnaie, itself derived from the Latin noun pastinaca, meaning "parsnip" or "carrot." The scientific name for the parsnip, "Pastinaca sativa," still reflects this history. "Pastinaca," in turn, traces back to "pastinum," a Latin word for a small gardening tool used to make holes in the ground for the insertion of plants, seeds, or bulbs. "Parsnip" may also remind you of the name of another edible root, "turnip," and there's a possible explanation for the resemblance. The Middle English spelling of "parsnip" ("passenep") may have been influenced by "nepe," the old form of "turnip."
