Pronunciation

Forms

denier m (plural deniers)[1] Old French dener, then denier from about 1175.[2][3] The Anglo-Norman forms include dener, denere and diner.[4]

Etymology

It is inherited from Old French dener, inherited from Latin dēnārius (“a silver coin worth ten asses”).[5][2][6][7] The Latin noun is an adjective meaning containing ten, used as a noun, from dēnī (“ten each”), the distributive of decem (“ten”).[2][8][9] In the Late Empire it was a small copper coin.[2][6] The old form gave the derivative denrée, and dénaire is a learned borrowing of the same Latin word.[2][1]

Cognate with Italian denaro, Old Occitan denier, Catalan diner, Spanish dinero and Portuguese dinheiro.[10][9]

Earliest recorded meaning

As dener it is found at the end of the 10th century in the Passion du Christ, meaning a Roman coin.[5][2]

Semantic evolution

From the Chanson de Roland (about 1100) the word also named a French coin, and until the 19th century coins of many values, even of silver and gold.[5][2][6] Hence the plural deniers for an unspecified sum of money (c. 1168, Chrétien de Troyes's Erec).[5][2] In li deniers saint Piere (c. 1175) and le denier Dieu (c. 1283) it named a payment made as an offering or contribution;[5][2][6] le denier Dieu was a levy on all bargains, used for pious works, and le denier à Dieu (1648) the earnest money paid when a bargain or a lease was made.[5][2][6] Le denier de la veuve, after the Gospel of Luke, is recorded in 1689 (Madame de Sévigné), and le denier du culte in 1906; only the last is still in use.[5][2]

Already in Old French the word was also a unit of weight (1256), and much later the measure of the weight of silk thread (1870).[5][2] In finance it named the rate of interest of a sum (1349, Machaut).[5][2] The English denier, for the French coin, dates from the early 15th century.[11]
