Forms
dēnārius m (genitive dēnāriī or dēnārī); second declension[1] The genitive plural is usually dēnāriōrum, but dēnārium in the partitive genitive, and a neuter dēnārium is also found.[2] It is abbreviated den and written with the sign X̶.[2]
Etymology
It is formed from dēnī (“ten each”) with the suffix -ārius; the noun is short for nummus (“coin”) with the adjective, the coin “containing ten” asses.[2][3][4][1] De Vaan derives the numeral decem (“ten”) from Proto-Italic *dekm and Proto-Indo-European *déḱm̥ (“ten”), cognate with Oscan δεκμας (dekmas, “tithe”).[5]
Earliest recorded meaning
The TLL finds it from Varro and Cicero on, perhaps already in Plautus;[3] Varro writes that a libella is a tenth of the nummus dēnārius.[2]
Semantic evolution
As an adjective it is containing or related to the number ten, as fistula dēnāria, a pipe ten inches round, in Vitruvius and Pliny the Elder.[2][6] With nummus or alone it is the denarius, the silver coin first worth ten asses, as Livy's Campanians ordered to pay 450 denarii; a Pompeian inscription seems to use it of bread worth a denarius.[2][1][4] It is also a measure of weight, as in Celsus, and dēnārius aureus is a gold coin worth 25 silver denarii, as in Petronius.[2]
Church Latin has dēnārius Sānctī Petrī, Peter's pence.[7] Köbler finds it throughout the early medieval law codes and capitularies.[8] English denarius was borrowed in the 1570s.[4]
