Ultimate origin
Latin (prō,tenus)

Pronunciation

  • Classical: [ˈproː.tɪ.nʊs][1]
  • Ecclesiastical: [ˈprɔː.ti.nus][1]

Forms

prōtinus (not comparable)[1] It is also spelled prōtenus, and Afranius has prōtenis.[2][3]

Etymology

It is formed from prō (“forward”) and tenus (“as far as”).[2][3][1] The TLL suggests it began in phrases such as ⟨*prō tenus īre⟩, with an old noun ⟨tenus⟩ “the length of a way”, and that the link with hāctenus and quātenus kept its vowel from being weakened.[4] Wiktionary connects that word with Proto-Indo-European *ten- (“to stretch”), as in tendō (“to stretch out”).[1]

Earliest recorded meaning

Plautus uses it of going straight on.[2][5] Lewis & Short note that the spatial sense, “forward, farther on”, is rare.[3]

Semantic evolution

Prōtinus is first “forward, straight on” from a point (Caesar, Virgil), also of continuing a process, and “directly on, from there on” in space.[2][3][1] Its common sense is temporal: “immediately, at once” (prōtinus ut, as soon as) and “from the very start”.[2][1] Quintilian also uses it for “by the same act, at the same time” and of a necessary consequence, “automatically”.[2]

Church Latin refers it to the spelling prōtenus.[6] Lewis & Short give statim, continuō and āctūtum as synonyms.[3]

Timeline

  • c. 250–184 BC – Plautus uses it of going straight on.[2][5]
  • 81–43 BC – Cicero uses it for “immediately”.[2][5]
  • c. 35–95/96 AD – Quintilian: “at the same time”, “necessarily”.[2][5]
