More About Spivakian Pronouns
The history of Spivakian pronouns goes back to the late 1970s, but they did not come to be called by that name until May of 1991 when a programmer added "spivak" as a gender option on the game LambdaMoo, causing the game to refer to players who chose it with the pronouns e, em, eir, eirs, and, emself.
