Forms
écu m (plural écus)[1] Old French escut (1080), then escu (about 1140); the modern spelling écu is first found in Malherbe in the early 17th century.[2][3][4]
Etymology
It is inherited from Old French escut, inherited from Latin scūtum (“shield”).[5][6][2][7] The Latin word, first for an oval shield, corresponds to Ancient Greek σκῦτος (skûtos, “leather, hide”), a word of unclear origin.[2] Wiktionary traces it to Proto-Indo-European *(s)kewH- (“to cover, protect”) or to *skey- (“to cut, split”).[1]
Cognate with Old Occitan escut, Spanish escudo, Portuguese escudo and Italian scudo.[8]
Earliest recorded meaning
In the Chanson de Roland (1080) escut is a shield: Tans cops a pris sur son escut bucler “he took so many blows on his bossed shield”.[5][8][9]
Semantic evolution
From the shield came the old senses “man-at-arms” (about 1150) and “protector” (about 1170, still in the 16th century), and the phrases porter écu “to fight” (about 1140) and rendre son écu “to admit defeat” (13th century).[2] In heraldry (1254), as in Medieval Latin, it named the shield-shaped field bearing the charges of a coat of arms, and in the 14th century the arms themselves.[2][4]
About 1340 it became the name of a coin, at first of gold, that bore the shield of France on one face;[2][4][7] Bloch and Wartburg date the first such gold coins to the reign of Saint Louis.[7] From 1641 the écu blanc or petit écu was a silver coin worth three livres, and écu came to mean money in general.[2][7] Many phrases about money went out of use with the coin, such as avoir des écus moisis “to be rich and miserly” (1690).[2] From 1794 the word also named a small paper size, watermarked with the coin.[2]
English took the coin name as ecu in 1704.[10]
