Pronunciation

  • Classical: [ˈeːr][1]
  • Ecclesiastical: [ˈɛr][1]

Forms

ēr m (genitive ēris); third declension[1] Plautus' manuscripts have irim and Nemesianus has erem;[2][3] de Vaan takes irim for a copying error for erim.[2]

Etymology

It is inherited from Proto-Italic *χēr-, inherited from Proto-Indo-European *ǵʰēr- (“hedgehog”).[2] The derivative ērīcius suggests that the stem was originally /ēr(-i)-/, which can be connected with the Greek word if Latin once had ⟨*hēr⟩; this may be a PIE root noun to a root meaning “to be excited, be bristly”, also seen in horior.[2]

Cognate with Ancient Greek χήρ (khḗr, “hedgehog”) (only in Hesychius), χοῖρος (khoîros, “porcupine”) and Albanian derr (“pig, swine”).[2]

Earliest recorded meaning

Plautus has it in the Captivi (184): modo uenare leporem, nunc irim tenes, “a moment ago you were hunting a hare, now you are holding a hedgehog”.[3][2]

Semantic evolution

The word is rare: after Plautus the TLL and Lewis & Short cite it from Nemesianus' poem on hunting, of the “spiny body” of the animal.[3][4] Beside it there were its derivative ērīcius, from Varro on, and erinaceus.[2][3]

Timeline

  • c. 250–184 BC – Plautus uses it of a hedgehog.[2][3][5]
  • second half of the 3rd century AD – Nemesianus writes of the hedgehog's spiny body.[3][5]
