solus

Etymology and origin of the Latin word solus

Confidence
Unknown
First attested
Naevius

Pronunciation

  • IPA (Classical): [ˈsoː.ɫʊs][1]
  • IPA (Ecclesiastical): [ˈsɔː.lus][1]

Forms

sōlus (feminine sōla, neuter sōlum); first/second-declension adjective (pronominal declension)[1] The genitive is usually sōlīus, but Terence and Cato have sōlī.[2][3]

Etymology

The origin is unknown.[4][1] The link with the reflexive sē proposed by Walde–Hofmann, Pokorny and Ernout–Meillet is hardly possible, according to de Vaan.[5][2] He considers instead the root *slH- of salvus and sollus “whole”, as *sōlH- “the whole, the one”.[5]

Earliest recorded meaning

Naevius speaks of people spreading gossip if they see a woman alone in the street.[2][5] Köbler dates Naevius c. 235–200 BC.[6]

Semantic evolution

In Classical Latin it was alone, having no companion, and lonely or forsaken.[2] It was only or sole, as Cicero's “the only one of the whole college”, and of places lonely or deserted.[2][7]

Isidore says that only the Father with the Son and the Spirit truly exists.[8] Through Old French it gave English sole “single”, and through Italian solo the musical solo.[4] It survives as French seul, Italian solo and Spanish solo.[1]

Timeline

  • c. 235–200 BC – Naevius uses it.[5][6]
  • 81–43 BC – Cicero uses it of the only one of a college.[7][6]
  • late 14th century – English sole “single” is recorded.[4]
  • 1690s – English solo is recorded.[4]
