Fascinating! Gender non-binary people have added a third pronoun: xi, which is expressed to delineate someone who identifies as non-cisgender, neither he nor she. “Is xi coming for dinner?” Raise your eyebrow or not, it’s very real. Visit San Francisco or Brooklyn and you’ll hear it in the gender-sensitive/inclusive vernacular. But will it ‘take?’ Languages are constantly evolving. Growing up in Denver we only heard “y’all” from the Texans on the ski slopes (and was considered a quirky abomination). Now it’s in the dictionary. Even 1950’s television shows a different way with words. Hard to believe, but “our” languages will one-day also be considered antiquarian!
