errō (present infinitive errāre, perfect active errāvī, supine errātum); first conjugation[1]
Etymology
It is inherited from Proto-Italic *ers-āje-, a verb formed from a noun Proto-Indo-European *h₁ers-o/h₂- (“erring, error”).[2][1][3] De Vaan notes that the shape matches the root Proto-Indo-European *h₁ers- (“to flow”), so that “flowing to and fro” could have given “erring” already in PIE.[2] Nussbaum connects instead the root meaning “to arrive”.[2] Cognate with Old Armenian եռամ (eṙam, “to boil; be restless”), Gothic 𐌰𐌹𐍂𐌶𐌴𐌹𐍃 (airzeis, “mistaken”) and Old High German irren (“to be mistaken”).[2][3][4]
Earliest recorded meaning
De Vaan's first attestation is Livius Andronicus, and the OLD's earliest citation, from Plautus, is of wandering about.[2][3] Köbler dates Livius Andronicus 280/260 to before 200 BC.[5]
Semantic evolution
It meant to wander, roam, of people and animals, as in Plautus, and in Ovid of things drifting or flitting.[3] In Cicero it meant to waver, be uncertain, and in Plautus to go astray, to be mistaken, and to stray from virtue, often to play down the offence.[3] Döderlein explains errāre as involuntary wandering by one who does not know the way, while vagārī and pālārī are wilful.[6]
Medieval Latin used it of wandering, getting lost and circling.[7] It survives in Italian errare, French errer and Spanish and Portuguese errar, and through Old French it gave English err about 1300.[1][8]
