Pronunciation

  • Classical: [ˈseː.ti.ʊs][1]
  • Ecclesiastical: [ˈsɛt.t͡si.us][1]

Forms

sētius (comparative, no positive form)[1] It is sometimes spelled sēcius.[2] Gellius quotes a line of Plautus with sectius.[2]

Etymology

It is inherited from Proto-Italic *sēto- (“late, slow”) with a comparative suffix: de Vaan explains the adverb as an ⟨-io-⟩ derivative of that adjective, from Proto-Indo-European *seh₁-to- (“late, slow”), perhaps from the same root as sērus (“late”).[3][1] The OLD gives the link with sērus only as possible.[2] Cognates include Old Irish sith- (“continuous”), Welsh hyd (“length”) and Old English sīd (“long”).[3] It was sometimes written ⟨secius⟩, as if it were a comparative of secus2 (“otherwise”), which brought it close to the real comparative sequius.[2]

Earliest recorded meaning

De Vaan dates it from Plautus, whose Cistellaria has it in the sense “later, more slowly”: a speaker delays himself by doing this.[3][2]

Semantic evolution

The sense “later, more slowly” is rare; the OLD marks it as apparent only.[2] In negative contexts it means to a lesser degree or less readily, as in Lucretius.[2] With quō and the subjunctive it means so as to delay or prevent something, as in an inscription (CIL 1.584).[2] The commonest use is nihilō sētius and similar phrases, “none the less, all the same”.[2][1] Perhaps under the influence of secus it also came to mean “otherwise”, as already in Plautus' Captivi.[2][1]

Timeline

  • c. 250–184 BC – Plautus, of doing something later or slower, and in the sense “otherwise”.[2][4]
  • 96–55 BC – Lucretius, in a negative clause, “less readily”.[2][4]
