Forms

īnstanter (comparative īnstantius, superlative īnstantissimē)[1]

Etymology

It is from Latin īnstāns (“pressing, urgent”) + -ter,[2] from the present participle of īnstō (“to press on, urge”),[3][4] a compound of in- and stō (“to stand”).[1] De Vaan traces the simple verb to Proto-Italic *sta-ē-je/o- and Proto-Indo-European *sth₂-eh₁-ie/o- (“to stand”).[5]

Earliest recorded meaning

It appears in Quintilian and Pliny the Younger;[3] Quintilian speaks of beginning several clauses “sharply and insistently” (ācriter et instanter).[3]

Semantic evolution

In Classical Latin it means vehemently, urgently, insistently;[2][3] Tacitus has the comparative of men fighting more fiercely, and Gellius the superlative of eager desire.[3]

Medieval Latin kept the sense “urgently, insistently”, as in a papal letter in the correspondence of Boniface and in Bede,[6] and added the sense “immediately, instantly”: British sources use it in this sense from 1217 on.[7][6][1]

Timeline

  • c. 35–95/96 AD – Quintilian uses it of speaking insistently.[3][4]
  • 98–115 AD – Tacitus uses the comparative.[3][4]
  • c. 165 AD – Gellius uses the superlative.[3][4]
  • 722 – A papal letter to Boniface uses the superlative.[6]
  • 1217 – An English Patent Roll uses it in the sense “immediately”.[6]
