ejaculate

ejaculate: [16] Etymologically, ejaculate means ‘dart out’. It comes from Latin ejaculārī, a compound verb formed ultimately from the prefix ex- ‘out’ and jaculum ‘dart, javelin’. This in turn was a derivative of jacere ‘throw’ (which itself combined with ex- to form ejicere, source of English eject [15]). The word’s original sense ‘throw out suddenly’ survived (or perhaps has revived) for a time in English, but essentially it has been for its metaphorical uses (‘emit semen’ and ‘exclaim’) that it has been preserved.

ejaculate (v.)

1570s, "emit semen," from Latin eiaculatus, past participle of eiaculari "to throw out, shoot out," from ex- "out" (see ex-) + iaculari "to throw, hurl, cast, dart," from iaculum "javelin, dart," from iacere "to throw" (see jet (v.)). Sense of "exclaim suddenly" is from 1660s. Related: Ejaculated; ejaculating; ejaculatory.
