A set of
gender-neutral third person singular pronouns created by
Michael Spivak, a mathematician who used them in his textbooks, which include
Comprehensive Introduction to Differential Geometry and
Calculus on Manifolds. They are used in a generic setting when someone's
gender is unknown - "the reader" is an example. Spivak pronouns are sometimes used online by individuals who do not wish their real life gender to be known.
