Forms
īnfitiae f pl (genitive īnfitiārum); first declension; only the accusative īnfitiās is used[1][2][3] Manuscripts often spell it īnficiae.[2][3]
Etymology
The OLD analyses it as from Latin in- (“not”) + *fatus (“said”) + -ia, comparing Ancient Greek φατός (phatós, “said, spoken”).[1] De Vaan, under fateor, likewise takes it to continue a form meaning “unsaid”, *in-fato-.[4] An ancient scholiast on Terence derived it from “not speaking”.[2]
Earliest recorded meaning
It is found first in Plautus,[5][4] where a character asks why someone chooses to deny what has been done.[1]
Semantic evolution
It occurs only in the accusative, in the phrase īnfitiās īre, “to deny”, with an accusative, an accusative and infinitive or quīn.[1][2][3] Except in early Latin it is very rarely used without a negative, so that nōn eō īnfitiās means “I do not deny”; it is not found in Cicero or Caesar.[3][6] Nepos has the parenthesis quod nēmō it īnfitiās, “which nobody denies”.[6][1]
It is also used of disowning obligations or claims, as when Plautus has a man refuse to acknowledge a debt; the jurist Gaius cites an oath that one does not deny a claim in bad faith.[1] Medieval writers kept the phrase, with variants such as in īnfitiās īre, and also used the noun for denial or defamation.[7]
Timeline
- c. 250–184 BC – Plautus uses īnfitiās īre of denying facts and debts.[1][5]
- c. 100–24 BC – Nepos writes quod nēmō it īnfitiās.[1][6][5]
- 59 BC–AD 17 – Livy uses it with an accusative and infinitive.[1][5]
- 140–180 AD – Gaius uses it of denying a legal claim.[1][5]
