Standard Esperanto features three third-person singular pronouns: “li”, corresponding to English “he”, “ŝi” corresponding to “she”, and “ĝi” corresponding to the English “it”. Some nonbinary Esperanto speakers may decide to simply use binary forms – either the same as their gender assigned at birth or the opposite. That doesn't make them any less nonbinary! Pronouns ≠ gender. The latter pronoun, similarly to its English equivalent, is considered by many not to be fit for referring to people, although some nonbinary people do use it anyway.

The standard pronoun “tiu” is proposed as a possible alternative to the binary “li” and “ŝi” and the not-personal “ĝi”, as it can simply mean “this person”. However, it is a correlative and not actually a personal pronoun.

The leading nonstandard pronoun is the neutral “ri”, which gained a lot of attention, especially among young speakers online. It is used as the default non-binary pronoun as well as simply the default pronoun by some, a role that was previously held by “li”. “Ri” is used as the default pronoun also on this very website.

Other nonstandard pronouns are: “ŝli” (created to be neutral, although rather in a binary way – as it is a short way of writing “he or she”), “gi” (a neutral pronoun being the personal version of “ĝi”), and “hi” (intended to be the masculine pronoun so “li” can become the neutral one). Unlike “ri”, these pronouns did not really come into frequent use.
