ejaculate

The word 'ejaculate' originates from the Latin verb ejaculari, meaning 'to throw out', which is a compound of the prefix e- ('out') and jaculari ('to throw a javelin'), derived from jaculum ('javelin'). This root, jac- (to throw), can be traced back to the Proto-Indo-European root ye-, also meaning to throw or impel. The literal sense of forcefully throwing something out evolved metaphorically in English. By the late 16th century, it first described the act of exclaiming words suddenly, as if throwing them out. The specific physiological meaning, referring to the sudden expulsion of semen, developed in the mid-17th century, maintaining the core concept of a sudden, forceful emission.
