Pronunciation

  • Classical: [ˈɛk.stɛr][1]
  • Ecclesiastical: [ˈɛk.ster][1]

Forms

exter (feminine extera, neuter exterum, comparative exterior, superlative extrēmus or extimus); first/second-declension adjective (nominative masculine singular in -er)[1] The masculine nominative singular is rare;[2][3] Lewis and Short also give exterus.[2][3]

Etymology

It is inherited from Proto-Italic *eksteros, inherited from Proto-Indo-European *h₁eǵʰsteros, formed from *h₁éǵʰs (“out”) with the contrastive suffix *-teros.[1][3] De Vaan derives ex (“out of”) from *eks and gives the superlatives ⟨extimus⟩, from ⟨*ekstamo-⟩, and ⟨extrēmus⟩, which replaced it; Oscan ehtrad (“outside”) has the form without /s/.[4]

Earliest recorded meaning

Köbler gives Lucretius as its first author,[5] who has vīs extera, “a force from outside”.[2]

Semantic evolution

It is outside or external, and mare exterum is the ocean as against the Mediterranean, as in Seneca.[2] It is also of another nation or family, foreign, as in an early law on “Latins or foreign nations”, and as a noun a stranger, as Columella's dogs that should snarl at strangers.[2][3] Lewis and Short note that the masculine nominative is post-classical and very rare.[3]

Church Latin glosses it “outward, external, foreign, strange”.[6] Köbler records it in early medieval laws and charters.[5]

Timeline

  • 96–55 BC – Lucretius of an outside force.[2][5]
  • 4 BC–65 AD – Seneca has mare exterum.[2][5]
  • 1st century AD – Columella of strangers.[2][5]
