Pronunciation

  • Classical: [deːˈɛr.roː], [ˈdeːr.roː][1]
  • Ecclesiastical: [deˈɛr.ro][1]

Forms

deerrō (present infinitive deerrāre, perfect active deerrāvī, supine deerrātum); first conjugation[1] In verse ⟨deer-⟩ is often scanned as one syllable.[2][3] It is also written derrō.[2][4]

Etymology

It is from Latin dē- + errō (“to wander, stray”).[2][4][5] De Vaan reconstructs the simple verb as Proto-Italic *ers-āje-, a denominative verb made to a noun Proto-Indo-European *h₁ers-o/h₂- (“erring, error”), which may be built on a root meaning “to flow”.[5]

Earliest recorded meaning

De Vaan and the OLD record it first in Plautus' Menaechmi, inter homines me deerrare a patre, of getting lost from one's father in a crowd.[5][2][6]

Semantic evolution

Lewis & Short call it rare but classical.[3] Cicero writes of people who had lost their way on a journey,[3][7] and Virgil of a he-goat that had strayed, vir gregis ipse caper deerraverat.[8] Figuratively it is to stray from a course of thought or action: Lucretius says some thinkers have strayed far from the truth,[6] and the Rhetorica ad Herennium uses it of not straying from a subject.[2] Seneca uses it of an archer who misses and of a man who goes wrong.[2] In Medieval Latin it still meant to lose one's way and to be mistaken.[9]
