What is the origin of the word cum? I'm trying to find the roots for its prevalent usage, especially in North America.

    Yes, I am referring to sperm. – Anderson Silva Jan 4 '11 at 20:42

    Such nonsense! It means "together with" and is actually a Latin preposition with the same meaning as in English. Oh you mean... – Cerberus_Reinstate_Monica Jan 4 '11 at 23:37
  • I thought it was short for "come to climax", but that's just a guess. – Andrew Grimm Mar 4 '11 at 23:16

It's an informal way of spelling 'to come', which can mean having an orgasm. How exactly that verb has become associated with sexual acts is unclear (to me). My best guess would be that it was commonly used in a phrase similar to:

I'm coming to an orgasm!

  • Was the first example specifically meant to testify of single-m usage? – Cerberus_Reinstate_Monica Jan 5 '11 at 3:40

    "The vicar's late coming!", said Mrs Brown, stirring her tea with the other hand. :) – user9682 Jun 22 '11 at 11:33

Etymonline explains:

cum (verb and noun) seems to be a modern (by 1973) variant of the sexual sense of come that originated in pornographic writing, perhaps first in the noun sense. This "experience sexual orgasm" slang meaning of come (perhaps originally come off) is attested from 1650, in "Walking In A Meadowe Greene," in a folio of "loose songs" collected by Bishop Percy. [...]

As a noun meaning "semen or other product of orgasm" it is on record from the 1920s. The sexual cum seems to have no connection with Latin cum, the preposition meaning "with, together with," [...].

To this, I will add that as far as the verb come is concerned, there are similar constructions in German (kommen) and French (arriver).

    P.S. Only used as a verb. Komen = to come in normal language. Funnily, it is not considered vulgar at all, as far as sexual terms go: it is rather neutral, because it is non-graphic. – Cerberus_Reinstate_Monica Jan 5 '11 at 12:22
  • In Japanese it is iku (to go). – user184130 Aug 16 '18 at 8:27

The Oxford English Dictionary has a definition for "Come" that first developed in 1440 that may have the answer for the double entendre that is "Cum."

When roasting certain grains during the malting process, the malt rises at the top and sometimes shoots off. This was referred to as the "come." Like in this example, "In Corn, [the Radicle] is that Part, which Malsters, upon its shooting forth, call the Come."

    Gee, who would ever have connected sexual activity with alcohol manufacturing? ;) – O.M.Y. Dec 31 '15 at 19:59

According to Etymonline.com, the noun cum has had its current sexual connotation since the 1920s. As a verb, it goes back much farther.


I always figured it was how illiterate people believed the verb "to come" (to orgasm) was spelled; resulting from confusion of shorted form of "scum" (as in "scumbag") referring to the male ejaculate.
