Pronunciation

  • Classical: [sɔˈdaː.lɪ.taːs][1]
  • Ecclesiastical: [soˈdaː.li.tas][1]

Forms

sodālitās f (genitive sodālitātis); third declension[1]

Etymology

It is from Latin sodālis (“companion”) + -tās.[2][1][3] De Vaan explains that noun as Proto-Italic *sweþāli-, an Italic derivative of a stem from Proto-Indo-European *sue-dhh1- (“custom, to get accustomed”), the combination also found in suēscō (“to become accustomed”); he also mentions an alternative connection with Ancient Greek ἴδιος (ídios, “own, private”).[4]

Earliest recorded meaning

It is first found in Plautus,[3][4] of a group of companions: nunc ego de sodalitate solus sum orator datus, “now I alone of the company have been sent as spokesman”.[2][5]

Semantic evolution

Its main classical sense is close association or intimate friendship, in political and social life: the Rhetorica ad Herennium and Cicero use it so, and Tacitus traces Nero's hatred of Vestinus to their intimate friendship.[2][6] Gellius uses the plural of companionships one is drawn away from.[5][7]

It also named an association: a religious brotherhood, as Cicero calls the Luperci “a wild and quite pastoral brotherhood”, and dining clubs, which the speaker of Cicero's De senectute recalls being founded for the Idaean rites in his quaestorship.[5][7][2] In a bad sense it was a secret electioneering gang: Cicero and his brother Quintus use it so, and Cicero reports a decree of the senate ordering the sodalitates to disband.[2][5][7]

In medieval Latin it meant companionship and a company, such as the company of the angels in Aldhelm.[8] Stelten gives “confraternity” and “guild”.[9] English sodality comes from it, directly or through French.[10]
