English is not and will probably never be my strongest subject, and having taken English as a Second Language over 20 years ago, I still have so much to learn about the language (especially those idiomatic expressions).
A random thought came up while I was having a zoom conversation with someone, and thought to myself, "if the person I was speaking with prefers a they/them pronoun, then I'm sure that conversation will just flow easily since use of they/them in a singular form is starting to get widespread usage." However, I wonder if our education system systematically has been aligned or is proactively working to align with that line of thought. I just remembered seeing a teacher back in the day correcting the term "themself" as incorrect because the word used was typically associated with multiple individuals. Also I do not remember when pronouns are taught in elementary school, and I'm sure as students mature they'll learn nuances about indefinite singular pronouns and the use of them, but I wonder at what point do schools need to enlighten students that they/them could be used as a singular pronoun for someone who does not use either he/him or she/her. Or has this always been taught and I just completely zoned out during this lesson?
I also wonder if this topic has implications as to how pronouns are used in other languages. In my limited knowledge of Spanish, a lot of terms are distinguished by feminine and masculine characteristics (e.g., el fuego, la raiz)...would there be grammatical implications for non-binary characteristics?
