 English, like most—but not all—languages, requires a great deal of what Marilyn Frye calls ‘sex marking’ (Frye 1983). For example, one cannot use pronouns to refer to a particular individual without knowing their sex. (Frye, in common with most feminists of the early 1980s, does not consider trans issues.  She also does not consider the possibility that pronouns like ‘he’ and ‘she’ might be a matter of gender, not sex.) Frye notes the absurdity of this.
