-This affects, for example, science-fiction authors writing about AIs or hermaphroditic aliens (which don't have a sex), or mystery authors writing about a crime suspect whose identity (and therefore, sex) is unknown. In these cases, [_she_ or](/2020/Apr/the-reverse-murray-rule/) _he_ are inappropriate, but the English language offers no alternative lacking its own downsides: _it_ is understood to refer to non-persons, _they_ gets conjugated as a plural, and neopronouns like [_ey/em/eir_](https://en.wikipedia.org/wiki/Spivak_pronoun)—or [_ve/ver/vis_](http://www.urticator.net/essay/0/30.html), as used in some of [Yudkowsky's juvenilia](https://intelligence.org/files/CFAI.pdf)—are hard to rally adoption for because pronouns are a [closed class](https://en.wikipedia.org/wiki/Part_of_speech#Open_and_closed_classes)—not something people are used to new members of being coined, in the way that people are used to seeing unfamiliar nouns and adjectives.
+[In a February 2021 Facebook post, Eliezer Yudkowsky inveighs against English's system of singular third-person pronouns](https://www.facebook.com/yudkowsky/posts/10159421750419228). As a matter of clean language design, English's lack of a gender-neutral singular third-person pronoun is a serious flaw. The function of pronouns is to have a brief way to refer back to entities already mentioned: it's more concise to be able to say "Katherine put her book on its shelf" rather than "Katherine put Katherine's book on the book's shelf". But then why couple that grammatical function to sex-category membership? You shouldn't _need_ to take a stance on someone's sex in order to talk about [her or](/2020/Apr/the-reverse-murray-rule/) him putting a book on the shelf.
