Cause'way or Cau'sey, n.

n. [O. Eng. calsey, Norm. Fr. calsay, Fr. chaussée, Pr. caussada, Sp. calzada, L. Lat. calceata, calciata, via calciata, properly a way paved with limestone, from Lat. calceare, calciare, to pave with limestone, from Lat. calx, calcis, limestone. The spelling causeway, which is now the common form of the word, owes its origin to an erroneous notion of its etymology.] A way raised above the natural level of the ground, by stones, earth, timber, fascines, &c., serving as a dry passage over wet or marshy ground, or as a mole to confine water to a pond, or restrain it from overflowing lower ground.
