Etymology and origin of the Latin word instar

Confidence
Uncertain
First attested
116–27 BC, Varro

Pronunciation

  • Classical: [ˈĩː.star][1]
  • Ecclesiastical: [ˈin.star][1]

Forms

īnstar n (indeclinable; found only as nominative or accusative)[2][1]

Etymology

The origin is uncertain; the OLD calls it doubtful and Wiktionary obscure.[2][1] Lewis and Short and Walde–Hofmann connect it with in- and the root of stō (“to stand”), as if “to stand in” and so “balance”.[3][4] De Vaan objects that a Latin infinitive was not used as a neuter noun, that the loss of the final ⟨-e⟩ would be unusual and that the meaning fits poorly, since ⟨instō⟩ means “to press on”; he suggests instead an old compound ⟨*(h₁e)n-steh₂-os⟩ “the standing in”, “the cost”.[4]

Earliest recorded meaning

De Vaan dates it from Varro,[4] who speaks of an author who removed from Mago's work the equivalent of eight books.[2] Köbler gives Cicero.[5]

Semantic evolution

It is the equivalent in measure, counterpart or equal, as Varro's laena, a cloak worth two togas in wool, and the equivalent in effect or worth, as Cicero's “that one day on which I returned to my country was for me the equal of immortality”.[2] With a genitive it expresses degree, as Catullus' man who has not the sense of a two-year-old boy, and ad instar is according to the pattern of something, as Apuleius' hair that gives back an image like a mirror.[2] Lewis and Short also give image or likeness.[3]

Church Latin uses it for image, likeness or appearance, and with a genitive “like, after the fashion of”.[6] In medieval Latin it is also a pattern, model or sample, and a copy.[7]
