Pronunciation

  • Classical: [soː.lɪˈtaː.ri.ʊs][1]
  • Ecclesiastical: [so.liˈtaː.ri.us][1]

Forms

sōlitārius (feminine sōlitāria, neuter sōlitārium, comparative magis sōlitārius, superlative maximē sōlitārius); first/second-declension adjective[1]

Etymology

It is from Latin sōlitās (“loneliness”) + -ārius,[2][1] and that noun comes from sōlus (“alone”).[1][3] Lewis & Short and VOLI derive it directly from the adjective.[4][5] De Vaan lists it among the derivatives of that adjective, from Varro on,[3] whose own origin is unclear: he finds a link with the reflexive pronoun hardly possible and suggests that it might belong with the root of salvus and sollus (“whole”).[3]

Earliest recorded meaning

It is first found in Varro,[3][2] who writes that bees are not solitary by nature, like eagles, but like human beings (apēs nōn sunt sōlitāriā nātūrā, ut aquilae, sed ut hominēs).[2][4]

Semantic evolution

Cicero uses it of a man living by himself in the country (sōlitārius homō atque in agrō vītam agēns) and writes that nature loves nothing solitary (nātūra sōlitārium nihil amat);[4] he also applies it to things that stand alone, such as an isolated judgement or a nature that is not joined with another.[2][6] Quintilian speaks of a solitary life spent in the shade,[2][4] Pliny the Younger of a dinner eaten alone,[4] and Gellius of a word with one sole meaning.[2] Lactantius and Minucius Felix use it of a deserted, solitary god.[4][7]

In Christian Latin the masculine became a noun for an anchorite or hermit.[8][9] In medieval Britain Bede and Alcuin use it of those who live alone, and bellum sōlitārium meant single combat.[10] It survives in Italian solitario.[6]
