Pronunciation

  • Classical: [ɪŋˈkʊr.si.oː][1]
  • Ecclesiastical: [iŋˈkur.si.o][1]

Forms

incursiō f (genitive incursiōnis); third declension[1]

Etymology

It is from Latin incurrō (“to run against”) + -tiō.[2][1][3] incurrō is a compound of currō “to run”, which de Vaan traces to Proto-Italic *korse/o- and Proto-Indo-European *kr̥s-e/o- (“to run”).[4]

Earliest recorded meaning

The TLL finds it first in Accius, then in Cicero, Caesar, Hirtius and Livy, who has it 23 times.[3]

Semantic evolution

It is an attack or assault, especially in war: Cicero writes of the onset and attack of armed men.[2][5] It is an incursion, inroad or raid: Caesar has part of a province laid waste by raids, and Livy a people making a hostile raid into Roman territory.[2][5] It is also a striking against, a collision: Cicero, setting out Epicurean views, writes of images by whose impact we see and think, and of the collision of atoms.[2][5] Church Latin glosses it attack,[6] and in Medieval Latin it is a fine imposed at discretion.[7] English incursion appears in the early 15th century.[8]

Timeline

  • 170–c. 90 BC – Accius uses the word.[3][9]
  • 81–43 BC – Cicero of an armed attack and of colliding atoms.[2][5][9]
  • c. 50 BC – Caesar of raids on a province.[2][9]
