This pronoun set was originated by Michael Spivak, a mathematician-educator who used them in a number of books. These books include The Joy of TeX, Comprehensive Introduction to Differential Geometry, and Calculus on Manifolds. It's also the favoured choice of certain people who have written about the subject, such as in Footnotes: Pronouns and in the Gender-Neutral Pronoun FAQ.
Spivak is one of the allowable genders on many MUDs and MOOs. Others might include some selection of: male, female, neuter, either, both, splat, plural, egotistical, royal, and 2nd. The selected gender determines how the game engine refers to a player.
In the event that E enters the English language proper, it will be the fourth word of one letter, the others being I, A, and O.
