Forms
īnsiliō (present infinitive īnsilīre, perfect active īnsiluī or īnsilīvī or īnsiliī, supine īnsultum); fourth conjugation, no passive[1] Plautus has the spelling insuliō.[2][3] Besides the perfect in -uī, forms in -īvī and -iī occur, and Quadrigarius has the imperfect insilibat.[3][4]
Etymology
It is from Latin in- + saliō1 (“to leap, jump”).[2][1][3] De Vaan traces saliō1 to Proto-Italic *sal-je- (“to jump”) and Proto-Indo-European *sh2l-ie/o-, but regards the reconstruction of the root as uncertain.[5] Cognate with Ancient Greek ἅλλομαι (hállomai, “to jump”) and Old Irish saltraid (“to trample”).[5]
Earliest recorded meaning
The TLL finds it from Plautus on,[3] whose Rudens has in scapham insiluimus, “we jumped into the skiff”.[2][4]
Semantic evolution
It means to leap into or onto something, with in and the accusative, with the plain accusative or the dative, or absolutely:[2][4] Lucilius has someone leap on a man's head, Caesar soldiers leaping onto the enemy's phalanxes, Livy a man leaping onto his horse, and Horace a leap into Etna.[2] Pliny the Elder says a vine shoot mounts the trellis, and Silius Italicus uses it of the sea.[2] Plautus jokes about leaping into the worst of torments, which Lewis and Short take as being crucified.[2][4]
From the sense of leaping on to attack, Apuleius has dogs springing at a man from all sides, and Statius has a goddess fall upon Thebes.[2] The frequentative īnsultō grew from it.[1]
