Gender Neutral Language

Gender-neutral language (gender-generic, gender-inclusive, non-sexist, or sex-neutral language) is language that attempts to refer neither to males nor females when discussing an abstract or hypothetical person whose sex cannot otherwise be determined. English does not have a system of grammatical gender for nouns in general, it instead uses gender-specific pronouns. Gender-neutral language in English includes but is not limited to the use of gender-neutral pronouns.
