Forms
temeritās f (genitive temeritātis); third declension[1]
Etymology
It is formed from Latin temere (“blindly, rashly”) + -tās.[2][1] De Vaan explains temere as a frozen locative of a noun ⟨*temes-⟩ “darkness”, from Proto-Italic *temesi and Proto-Indo-European *temH-os- (“darkness”): “in the dark”, hence “blindly”.[3] Cognate with Sanskrit तमस् (támas-, “darkness”) and Lithuanian tamsà (“darkness”), and within Latin with tenebrae.[3]
Earliest recorded meaning
Plautus, Mercator: ineptia stultitiaque adeo et temeritās, “folly and stupidity and rashness” among the vices of lovers.[2][3]
Semantic evolution
Its main sense is rashness and thoughtlessness, and of opinions their lack of foundation (Cicero).[2] In a better light it is boldness, readiness to take risks, as when Celsus says that some remedies must be seized with a certain boldness.[2] An older sense, from temere “at random”, is chance or accident: in Pacuvius some claim that everything happens by chance, and Cicero contrasts temeritās with order in nature.[2][4]
Church Latin glosses it “rashness, chance, recklessness, accident”.[5] In medieval law it was a serious offence punished by a fine, especially bloodshed.[6] English temerity dates from the early 15th century.[7]
