Also no longer with us: the concept of binary sex. Just a few years ago, the term “gender” began substituting for “sex” in common usage; from there, the word took on meaning as a form of identity. At the time, we were told gender was a social construct. The latest instruction, however, confirms the polar opposite: It’s inborn. Moreover, gender doesn’t any longer describe traditional sex; and beyond distinctions such as “co,” “en” “xie” “yo,” and “ze,” now upon us is the era of “noun-self pronouns.”
