calcaneus (n.)

"loan translation of a foreign word or phrase," 1937, from French calque, literally "a copy," from calquer "to trace by rubbing" (itself borrowed in English 1660s as calk "to copy by tracing"), a 16c. borrowing by French of Italian calcare, from Latin calcare "to tread, to press down," from calx (1) "heel" (see calcaneus). 

"road or path raised above the natural level of the ground," as a dry passage over wet places or along the top of an embankment, 1570s, from Middle English cauceweye "raised road" (mid-15c.). The first element is from Anglo-French cauce, Old North French cauciee (12c., Modern French chaussée), from Vulgar Latin *via calciata "paved way," from Latin calcis, genitive of calx (2) "limestone," or Late Latin calciare "to stamp with the heels, tread" (on the notion of a road or mound across marshy ground made firm by treading down), from Latin calx (1) "heel" (see calcaneus). For second element, see way (n.).
