# bisexual
## English
### Alternative forms

* bi-sexual

### Etymology

From bi- +‎ -sexual, via the French bisexuel (bi-, sexuel). Attested since 1792 as a synonym in botany for "hermaphroditic" ("having male and female parts"). First used of sexuality in Richard von Krafft-Ebing's 1886 Psychopathia Sexualis (in German) and Charles Gilbert Chaddock's 1892 English translation thereof, due to the theory that people were naturally attracted to the opposite sex and so the brain or mind of a person attracted to "both" sexes (or to the same sex) must be partly of another sex and thus "hermaphroditic".

    But it does not agree with our idea of orthodox sexual reproduction, since many generations may pass without the appearance of males. The reproductive products at such times are purely feminine—that is, eggs which develop without having been fertilized by a male cell, the spermatozoan. We may distinguish this form of reproduction from sexual reproduction, in the restricted sense, or bisexual reproduction, as unisexual or parthenogenetic reproduction.

* ↑ In Palisot de Beauvois's "Memoir of Observations on the Plants denominated Cryptogamick", read February 17, 1792, and published in the 1793 Transactions of the American Philosophical Society, page 211, says "It appears that the urn is a bisexual flower, containing a capsule more or less pedunculated, according to the length of the tube." Other earlier uses are in Robert John Thornton's Reformed Sexual System of Linnaeus in The Philosophical Magazine (1808), and in James Lee's Introduction to the Science of Botany (1810), which includes an early call to eschew hermaphrodite in favor of bisexual.
* ↑ Besides Krafft-Ebing's and Chaddock's works, e.g. the 1906 English translation of Otto Weininger's 1903 Geschlecht und Charakter (Sex and Character) says certain people have "from the beginning an inclination to both sexes; they are, in fact, bisexual." The 1915 edition of Havelock Ellis's Sexual Inversion also shows the sense development: "there is sexual attraction to both sexes, a condition formerly called psychosexual hermaphroditism, but now more usually bisexuality."
