Pronunciation

  • Classical: [ˈoːs.kʊ.ɫũː][1]
  • Ecclesiastical: [ˈɔs.ku.lum][1]

Forms

ōsculum n (genitive ōsculī); second declension[1] Plautus also has ausculum and the syncopated osclum.[2][3]

Etymology

It is a diminutive, from Latin ōs (“mouth”) + -culum, “little mouth”, as Varro already saw.[4][3][1] De Vaan reconstructs ōs as Proto-Italic *ōs- and Proto-Indo-European *h₃eh₁-os (“mouth”), cognate with Sanskrit आस् (ā́s, “mouth”) and Hittite aiš (“mouth”).[5]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[5][6] who uses it for a kiss: sat est ōsculī mihi.[4]

Semantic evolution

Ōsculum is a kiss, in phrases such as ōsculum ferre, dare, fīgere or imprimere and ōscula iungere, to exchange kisses.[4] In poetry and post-Augustan prose it is also the mouth or lips, especially as used in kissing (Virgil: the children hang on their father's lips), and a little or pretty mouth.[4][2] Döderlein calls ōsculum a friendly kiss, suāvium a tender one and bāsium an ardent one.[7]

Church Latin glosses it “kiss”.[8] In medieval Latin it was also a bridegroom's gift to his bride and the deed recording it.[9] In New Latin it is a small opening.[1]

  • c. 250–184 BC – Plautus: sat est ōsculī mihi.[4][6]
