causeway

Etymology

It is inherited from Middle English cauceweye, also cauciwey,^[2][3][4][5] formed from Middle English cauce + wey, that is causey and way.^{[6][7][8][9][10]} The first element, now archaic or dialectal,^[11][10] is from Anglo-Norman causee, also caucé, and Old French cauchie, now French chaussée,^[6][3][12] from Medieval Latin calciāta (“causeway, built-up road”), recorded from the 9th century and short for via calciāta (“paved road”).^[6][3][2][9] This is probably the feminine of an adjective formed from Latin calx (“lime, limestone”), the material used for paving roads,^{[6][11][10][12][2]} which is also the source of chalk, calcium and calculate.^[10] Skeat derived it instead from the Latin verb calcō (“to tread”), from the word for heel, and Etymonline gives both explanations, the second on the notion of a road made firm by treading.^[13][3] Merriam-Webster's “Book of Word Histories” notes a 10th-century document describing such a road as made of stone fragments trodden underfoot, but judges the limestone origin more probable, since the Romans used lime mortar in boggy ground.^[9] The second element goes back to Old English weg.^[14]

Earliest recorded meaning

A raised road or path across low or wet ground or water: 1440, in the Promptorium Parvulorum.^[6][2] Barnhart finds the simple word cauce probably before 1330, in Arthour and Merlin.^[2]

Semantic evolution

According to the Oxford Dictionary of Word Origins, the first recorded sense of causey was a mound, embankment or dam, and a causey way was a way along such a mound, or a raised footpath beside a road that might be flooded in wet weather; it was later contracted to causeway.^[11] The contracted form is recorded from 1571.^[2][3] The word was used from 1593 of highways, originally raised and paved, especially the Roman roads,^[6][4] and figuratively from 1597.^[6] From 1600 to 1878 it could also mean an embankment or dam holding back water.^[6] In Scotland it has meant a paved street or cobbled pavement since at least 1727.^[6] Johnson (1755) entered it under causey, saying that causeway had lately been written "by a false notion of its etymology",^[15] and Weekley likewise called it a folk etymology for causey.^[16] The verb, to make a causeway across an area, is recorded from 1703 in Massachusetts, and to pave with small stones from 1715 in Scotland.^[6]
