Pronunciation

  • IPA (Classical): [ˈĩː.fraː][1]
  • IPA (Ecclesiastical): [ˈiɱ.fra][1]

Forms

īnfrā (comparative īnferius, no superlative)[1] An inscription has the older form infera.[2]

Etymology

It is a contracted form of ⟨īnferā⟩, the ablative singular feminine of īnferus “lower”, like suprā and extrā.[2][3][4] Köbler traces ⟨īnferus⟩ to Proto-Indo-European ⟨*n̥dʰero-⟩ “lower”.[5]

Earliest recorded meaning

The OLD's earliest citation for the adverb is from Cato, “below”.[2] Köbler dates Cato 234–149 BC.[5]

Semantic evolution

As an adverb it meant below, underneath, as in Cato, and in Lucretius beneath the reach of the senses, and Quintilian used it for later, further on, and Pliny the Elder for lower in degree.[2] As a preposition with the accusative it meant below, as in Cicero, later than, lower in number, as in Caesar, inferior to, as in Terence, and beneath someone's dignity, as in Cicero.[2]

British Medieval Latin used it for below, further down a page or list, and below the surface.[6] It survives in Italian fra, and English uses infra in footnotes for “further on” and the prefix English infra-.[1][7]
