Forms
ēiaculor (present infinitive ēiaculārī or ēiaculārier, perfect active ēiaculātus sum); first conjugation, deponent[1]
Etymology
It is formed from Latin ex- + iaculor, from the prefix ex- (“out”) and iaculor (“to throw, hurl”),[2][3][4] which comes from iaculum (“javelin, dart”), from iaciō (“to throw”).[5]
Earliest recorded meaning
Its first user is Ovid (43 BC–18 AD), in the Metamorphoses, where something shoots out long jets of water (longas eiaculatur aquas).[6][7][8]
Semantic evolution
It meant to shoot or hurl out with force: of water, of blood spurting high, and, in Pliny the Elder, of a shadow cast into a forum.[6][7] L&S calls it rare and not found before Augustus.[6] Scribonius Largus has it with passive force, and Aulus Gellius uses the active form eiaculaverat.[2][3]
Medieval writers kept the sense “to hurl, fling”,[9] also of thunderbolts and weapons in Polish texts of the 16th century.[10] English made ejaculate from its past participle in the 1570s, first for emitting semen.[5]
