Ey/em

The set is usually called Spivak, after a mathematician who used a capitalised version of it in a typesetting manual and did not coin it. Ey was coined in 1975 by Christine M. Elverson of Skokie, Illinois, who formed it by dropping the th from they. Elverson won a contest run by the Chicago Association of Business Communicators with it, and the article that first reported the result treated the whole exercise as a joke.

What the record holds for Ey/em

First documented

1975

Christine M. Elverson coined ey, em and eir in 1975 by dropping the th from they, them and their, winning a Chicago Association of Business Communicators contest. Judie Black reported it in the Chicago Tribune on 23 August 1975. Related forms are older: a January 1890 editorial by James Rogers gives e, es and em.

How common

Not measured

How ey and em decline

Elverson made all three core forms the same way, by taking the th off they, them and their, which is why the paradigm looks familiar to a reader who has never seen it before.

Ey rhymes with the letter a and is a homophone of it, which is the one thing about the set that has to be learned rather than guessed. The Chicago Tribune's report of the contest on 23 August 1975 used the pronouns in its own copy: a person's sentences would sound smoother since ey would not clutter them with the old pronouns, and if ey tripped up in the new usage, ey would have only emself to blame.

The original ey has been argued to be preferable to e, which is the shorter variant, on the ground that e is pronounced the same as he in any position where he, him and his lose their h.

Where the ey set was coined

The Chicago Association of Business Communicators ran a contest to find replacements for she and he, him and her, his and hers. Christine M. Elverson of Skokie, Illinois, won it in 1975 with ey, em and eir. Judie Black reported the result in the Chicago Tribune on 23 August that year, on page 12 of section one, and closed the piece with a rival entry: a contestant from California who proposed uh, on the reasoning that a person who is not a he or a she is uh, something else. Black signed off by calling that so much of eir humour.

The competition had a specific audience. It was run by an association of business communicators for the practical problem of writing about an unnamed employee.

Which variants the record separates

The history is unusually tangled because the pronouns appear to have been created independently more than once. Wikipedia separates three variants as being in current use, plus a fourth from a novel, and the differences between them are small enough to matter.

The earliest is an editorial by James Rogers from January 1890, which derived e, es and em from he and them in answer to the rival proposal thon. The Scottish novelist David Lindsay arrived at ae and aer independently in A Voyage to Arcturus, using them for beings he described as unmistakably of a third positive sex.

Two proposals landed in 1977. The poet and linguist Lillian Carlton wrote to the journal American Speech to argue against a set built on the long e sound, invented by an American professor Wikipedia identifies as probably Donald MacKay, on two grounds: said quickly it comes close to the non-standard hisself, and ee sounds too much like he. Her own preference was for the existing word one. In the same year Jeffery J. Smith, an emeritus professor of philosophy and humanities at Stanford University writing as Tintajl jefry, proposed em as a personal noun-pronoun carrying no indication of sex, age or number, and extended it to forms of address as well.

MacKay's sets reached print in American Psychologist in May 1980, in a study measuring how often readers misread the gender of a person in textbook paragraphs written with he meaning he or she, against three epicene alternatives.

How Spivak gave the set its name

Michael Spivak, an American mathematician, wrote the AMS-TeX manual The Joy of TeX in 1983 using E, Em and Eir. His forms were Elverson's with the capitalisation of one of MacKay's sets, and the book carried them to a readership of mathematicians and typesetters. The name attached to the pronouns from there.

Spivak did not coin them and the record does not claim he did. Wikipedia's own article carries a maintenance notice, added in September 2024, asking for more citations, and describes the precise history as unclear.

How LambdaMOO put the pronouns in software

In May 1991 a programmer named Roger Crew added spivak as a gender setting for players on LambdaMOO, a text-based virtual world. Setting it made the game engine refer to a player as e, em, eir, eirs and emself. Crew added it alongside several other invented gender settings in order to test changes to the software's pronoun code, and left it in as a novelty.

To Crew's surprise the spivak setting caught on among the players while the others were mostly ignored. A pronoun set moved from a printed proposal into working code, and the code then produced sentences whether or not anyone had learned the paradigm. On LambdaMOO the forms became standard practice in help texts, in references to a guest whose gender was unknown, and in references to a person whose gender was known but not being disclosed. Wikipedia records that this usage has been declining since 2000, and marks that sentence as needing a citation.

Spivak is one of the selectable genders on many multi-user dungeons and MOOs, beside options such as neuter, either, both, plural, royal and second. Wikipedia notes that a virtual community is sometimes where a person first encounters genderless pronouns, and sometimes where they first experiment with presenting themselves in a Genderqueer or Transgender way. Nomic games, which are played by amending their own rules, use the set in their rulesets to refer to an indefinite player.

Where ey has been used since

The Elverson forms were revived by writers applying the original th-dropping rule rather than by anyone following Elverson. Eric Klein used them in the legal code he wrote for Oceania, a planned micronation, in 1993. John Williams's Gender-neutral Pronoun FAQ of 2004 promoted the Elverson set, reaching it through Klein, in preference to the other contenders then circulating on Usenet.

Wiktionary's dated citations are thinner than the publication list. It carries the Chicago Tribune piece of 1975, a message to the newsgroup alt.yoga of 22 December 1996, and one to alt.cellular of 25 November 1997 in which a mobile user pays a long-distance fee for a call carried from eir home area. The pronoun sense was taken to Wiktionary's request-for-verification process in October 2011 and passed, on the strength of the books Wikipedia lists; other senses of the same spelling, an island and a state of fear, were taken there later and failed.

The books divide by variant. The Elverson forms appear in Eric Klein's Laws of Oceania, in R. J. Edwards's webcomic Riot Nrrd between 2009 and 2014, and in a 2011 novel by C. J. Carter. The LambdaMOO forms appear in Steven Shaviro's Doom Patrols of 1997, Julian Dibbell's My Tiny Life of 1999, Jane Love's 2000 essay on writing centre pedagogy, Elizabeth Hess's Yib's Guide to MOOing of 2003, Sue Thomas's Hello World of 2004, the shared-universe project Orion's Arm, Ann Leckie's novel Provenance of 2017, and Maia Kobabe's memoir Gender Queer of 2019. Four of those eight are about virtual worlds.

Common questions

Questions about Ey/em

How is ey used in a sentence?
Ey fills the subject slot, em the object slot, eir the possessive, eirs the standalone possessive and emself the reflexive: ey laughs, I hugged em, eir heart warmed, that is eirs, ey loves emself. Ey is a homophone of the letter a rather than of they.
Who actually coined the Spivak pronouns?
Christine M. Elverson of Skokie, Illinois, coined ey, em and eir in 1975 by dropping the th from they, them and their. Michael Spivak, whose name the set carries, used a capitalised version in a typesetting manual eight years later and is not recorded as having invented anything. Wikipedia describes the precise history as unclear and lists at least seven separate proposals of similar forms between 1890 and 1991.
What is the difference between ey and e?
Only the subject form. Elverson's 1975 set uses ey and the LambdaMOO setting of 1991 uses e, and both continue em, eir, eirs and emself. The argument for ey is phonetic: in any position where he, him and his lose their h, e is pronounced the same as he, which defeats the purpose of the set.
Why are they called Spivak pronouns?
Because Michael Spivak used E, Em and Eir throughout The Joy of TeX, the AMS-TeX manual he wrote in 1983, which put the forms in front of a readership of mathematicians and typesetters. The name was then carried into the LambdaMOO software, where the gender setting itself is called spivak.
Where did the LambdaMOO setting come from?
A programmer called Roger Crew added spivak as a player gender setting on LambdaMOO in May 1991, along with several other invented settings, in order to test changes to the software's pronoun code. He left it in as a novelty. It caught on among the players while the other test settings were ignored, and the game engine then produced e, em, eir, eirs and emself automatically for anyone who chose it.

The evidence behind the word

How thoroughly Ey/em has been counted

Not how common the word is. How much of a population anybody has actually measured it across, on a six-step scale where each step is defined by the kind of evidence it takes to reach it, never by a score. The full method.

NM

Not measured (umbrella/descriptor)

Ey/em sits outside the six steps. Institutional descriptor or umbrella concept not used as a self-identification label in surveys. There is nothing for a survey to count, which is a fact about the word rather than about how many people it fits.

Gender Census and USTS are self-selected community samples (shares of the gender-diverse community, multi-select, checkbox lists change yearly), not population prevalence. Only Williams Institute and Ipsos provide general-population estimates. Culture-specific figures mix census counts, academic studies, and advocacy estimates - each row cites its source.
