Forms
ūsūrārius (feminine ūsūrāria, neuter ūsūrārium); first/second-declension adjective[1]
Etymology
It is from Latin ūsūra (“use; interest”) + -ārius.[2][1] De Vaan lists it, with ⟨ūsūra⟩, among the derivatives of ūtor (“to use”), which goes back to Proto-Italic *oit-e/o- (“to use”); a link with Proto-Indo-European *h₃eit- (“to take along”) is uncertain, though he finds Tichy's theory of a shift from “fetch” to “use” attractive.[3]
Earliest recorded meaning
Plautus has it first,[3] in the Amphitruo, where the substitute Amphitruo leaves with Alcumena, a wife only on loan (uxore usuraria).[2]
Semantic evolution
In Plautus it means “had for use for a while, on loan”: a boy to be got for one's use, and aera usuraria, borrowed money.[2] Fronto still has the old sense, of a sum left to wards for their use rather than as their own.[2] In the jurists of the Digest it means “bearing interest”, of a debt or a debtor.[2][4]
In Medieval Latin it was used as a noun for a moneylender,[5] and British sources use it of lending at excessive interest, and of the usurer.[6] English usurer comes from this medieval noun, through Anglo-French.[7] French usuraire and usurier and Italian usurario and usuraio continue it.[1]
Timeline
- c. 250–184 BC – Plautus uses it of people had on loan and for borrowed money.[2][8]
- 100–170 AD – Fronto uses it of money left for use rather than ownership.[2][8]
- before 223 AD – Ulpian uses it in the Digest of a debt bearing interest.[2][8]
- c. 1167 – A British text speaks figuratively of an increase of virtues like interest on a loan.[6]
- late 13th century – English borrows the noun, through Anglo-French, as usurer.[7]
