A personal pronoun is a form of speech that stands in for a person or group of people. She is having opinions online; they are fighting in the comments; and, of course, as in the Prince song made famous by Sinead O’Connor, “Nothing Compares 2 U.” Nonbinary pronouns, as well — often the singular “they” and “them” — have become widespread.
A 2019 Pew Research study found already that one in five Americans knew someone who uses nonbinary pronouns. And then there are neopronouns.
A neopronoun can be a word a created to serve as pronoun without expressing gender, like “ze” and “zir.” A neopronoun can also be a so-called “noun-self pronoun,” in which a pre-existing word is drafted into use as a pronoun.
