causeway: [15] Etymologically, a causeway is a road paved with limestone. In late Middle English, the word was causey way, causey coming via Anglo-Norman *cauce from Vulgar Latin *calciāta, an adjective derived from Latin calx ‘limestone’ (source also of English chalk, calcium, and calculate). The simple form causey ‘causeway, path’ survived dialectally well into the 20th century, and its French relative chausée, ‘road’ is still very much alive.
