Pronunciation

  • Classical: [asˈsɪ.li.oː][1]
  • Ecclesiastical: [asˈsiː.li.o][1]

Forms

assiliō (present infinitive assilīre, perfect active assiluī); fourth conjugation, no supine stem, third person-only in the passive[1] It is also spelled adsiliō.[2][3]

Etymology

It is from Latin ad- + saliō1 (“to jump”).[2][1] De Vaan traces that verb to Proto-Italic *sal-je- (“to jump”) and Proto-Indo-European *sh₂l-ie/o- (“to jump”), but regards the exact form of the root as uncertain.[4] Cognate with Ancient Greek ἅλλομαι (hállomai, “to jump”).[4]

Earliest recorded meaning

The earliest example Lewis & Short and Georges give is figurative: Cicero, in De oratore, advises that one should not leap straight into a particular kind of speech.[3][5]

Semantic evolution

It is mostly poetic.[3] Phaedrus uses it of someone leaping up with joy at a promised gift, and Columella of a stallion mounting a mare.[2][5] Ovid and Statius apply it to water and waves dashing up against something, as the Aegean against its islands in Statius.[2][5] In accounts of fighting it meant to rush to the attack: Tacitus writes of men who attacked unexpectedly, and Statius uses it with an object, to assault someone.[2][5] Seneca the Elder uses it of throwing oneself gladly into a pursuit.[2][5]
