Pronunciation

  • Ecclesiastical: [ˈaː.li.as][1]

Forms

aliās (not comparable)[1]

Etymology

It is an adverb from alius (“other”), in form an old feminine accusative or genitive, like forās.[2][1] De Vaan traces ⟨alius⟩ to Proto-Italic *aljo- (“another”) and Proto-Indo-European *h₂élyos (“other”), cognate with Ancient Greek ἄλλος (állos, “other”), Gothic 𐌰𐌻𐌾𐌹𐍃 (aljis, “other”) and Old Irish aile (“other”).[3]

Earliest recorded meaning

Plautus, Asinaria: ut vōs, ut aliās, pariter nunc Mārs adiuvet, “that Mars may help you now as at other times”.[2][4]

Semantic evolution

Its first sense is at another time, on other occasions, and Suetonius has it of “before” or “afterwards”, aliās … aliās is “at one time … at another”, as Plautus' man who asks now thirty minae, now a talent.[2] From that it is in other cases, otherwise (Sallust: leisure and wealth, desirable otherwise, became a burden), and in Pliny the Elder “besides”, “else” and “all the same”.[2] The jurists use it of place, “elsewhere”, and of manner, “in another way”.[2]

Church Latin glosses it “elsewhere, at another time, at other times”.[5] English alias (mid-15th century), “otherwise called”, comes from its later sense “in another way”.[6]

Timeline

  • c. 250–184 BC – Plautus of other times.[2][4]
  • 86–34 BC – Sallust in the sense “otherwise”.[2][4]
  • 23/24–79 AD – Pliny the Elder in the senses “besides” and “else”.[2][4]
  • 140–180 AD – Gaius in the sense “elsewhere”.[2][4]
