“Calling pronouns like ze and hir “new pronouns” or “neopronouns” is misleading too, because these words are relatively old. They may be enjoying a renaissance today, but ze appears in 1864, introduced by someone known only by the initials J. W. L., and hir first popped up a century ago, invented, or at least introduced to readers in California, by the editor of the Sacramento Bee on August 14, 1920.”
