History
Etymology
Originally a borrowing of Italian terrapieno (“earth-fill(ed)”), later altered after the model of French terreplein (now terre-plein). Its former misspellings arose from confusion of the second element of the name with Italian piano or French plain, plane (“flat, level”) based on the appearance of the earth-filled central platforms of walls.
