Pronunciation

  • Classical: [ˈraː.reː][1]
  • Ecclesiastical: [ˈraː.re][1]

Forms

rārē (comparative rārius, superlative rārissimē)[1]

Etymology

It is from Latin rārus (“loose, scattered; rare”) + -ē.[2][1] De Vaan lists it among the derivatives of rārus, whose own origin he finds unclear.[3]

Earliest recorded meaning

It is first found in Plautus, meaning “seldom”: the Rudens has rare capitur, “it is seldom caught”.[2][4][3]

Semantic evolution

Columella uses it in the literal sense “thinly, sparsely”, of sowing seed at wide intervals and of a bag woven with an open texture.[2][5] According to Gellius, Varro did not accept rare as an adverb,[2] and the usual adverb for “seldom” was rārō, with which the comparative and superlative are shared.[2] Köbler records it only from Apuleius.[6]

In British Medieval Latin it means “seldom, rarely”: Anselm writes that his letters greet his correspondents rarissime though his memory sees them every day.[7]

Timeline

  • c. 250–184 BC – Plautus uses it for “seldom”.[2][6]
  • 1st century AD – Columella uses it for “sparsely, loosely”.[2][5][6]
  • c. 165 AD – Gellius reports that Varro rejected it as an adverb.[2][6]
  • 2nd half of the 11th century–1109 – Anselm uses the superlative rarissime in his letters.[7][6]
