cunnilingus

Etymology

From Latin cunnilingus (literally “cuntlicker”). The meaning shift, not yet complete in the early twentieth century, perhaps derives from figurative uses where the name for a person stands for the name of a practice.

noun

1. (obsolete) Someone who performs oral sex on the vulva.
   The stinking breath, hoarse voice, and snoring respiration of the cunnilingus, fellator and fellatrix, the effeminate, piping tone of the cinædus and irrumator, which excited the special scorn of the early satirical writers, were doubtless the expression of a catarrhal pharyngolaryngitis acquired in the discharge of their filthy practices. 1887, John Noland Mackenzie, “Carcinoma of Larynx”, in Albert H.

   The foul mouth, hoarse voice, and snoring respiration of the cunnilingus, fellator and irrumator have been thought to indicate syphilitic affections of the throat, but, as I have suggested elsewhere, they were doubtless the symptoms of a catarrhal process acquired in the discharge of their filthy occupations. 1887, John Noland Mackenzie, “Syphilis of the Larynx, Trachea, and Bronchi”, in Albert H. Buck, editor, A Reference handbook of the medical sciences, embracing the entire range of scientific and practical medicine and allied science, volume 4, New York: William Wood & Company, page 439b
