Confidence
Established
Formation
Derivation
First attested
204–169 BC, Ennius
Ultimate origin
Proto-Indo-European (*(H)ieh₁-)

Pronunciation

  • Classical: [ˈja.kʊ.ɫũː][1]
  • Ecclesiastical: [ˈjaː.ku.lum][1]

Forms

iaculum n (genitive iaculī); second declension[1] It is also spelled jaculum.[1][2]

Etymology

It is formed from iaciō (“to throw”) with the instrument suffix -ulum, “a thing for throwing”.[3][4][1] Varro says it is made to be thrown.[4] De Vaan derives ⟨iaciō⟩ from Proto-Italic *jak-i- (“to throw”) and Proto-Indo-European *(H)ieh₁- (“to throw, let go”), cognate with Ancient Greek ἵημι (híēmi, “to send, throw”).[5]

Earliest recorded meaning

Köbler gives Ennius as its first author;[6] Sisenna has men who used up their javelins quickly and turned to swords.[3]

Semantic evolution

It is a throwing spear or javelin, as Cicero's “you will not see the sun for the mass of javelins and arrows”.[3][2][1] It is any other missile, as Apuleius' showers of flowers thrown to please the goddess, and in Ovid apparently a casting net: “here fish are caught with the net, there with hooks”.[3][1] Wiktionary adds the net of the rētiārius.[1]

Church Latin glosses it “arrow, dart, javelin”, and Medieval Latin “arrow”.[7][8]
