“Neopronoun with a nod to folklore”: That was the 28-Across clue in the September 23, 2022, New York Times crossword, and until I completed the fill I was stumped.
I was familiar with the term neopronoun: “a category of neologistic English third-person personal pronouns beyond ‘he,’ ‘she,’ ‘they,’ ‘one,’ and ‘it,’” according to a Wikipedia entry on the topic. I’d even read Dennis Baron’s 2020 book, What’s Your Pronoun? Beyond He and She, which includes a handy chart.
Fae and faer are down at the bottom. Baron does not explain their origin or significance, so I did some more research.
