No, that title doesn’t contain a typo. The New York Times has just used the newly coined honorific Mx. that identifies neither marital status nor gender.
Maybe Mx. could also be useful for sci-fi and fantasy authors when writing politely about aliens or supernatural beings of indeterminate sex? Should Time Lords/Ladies like Doctor Who henceforth be called Mx. Who? Or Missy be called Mx. Master? No, that sounds like a kitchen blender. I’ve been thinking about this for far too long, as you can see…
