This is a big thing right now with all this debate about gender politics. Singular (and gender neutral) "they" has been in common usage for a long, long time, but grammar sticklers often don't like it.
Feels like in this age “they” is the safest word to use. I think gender equality should be automatic, a non issue, common sense. (Sadly not the case)
But all this new gender neutral and additional “genders” that people identify with confuse the hell out of me
I had no idea! Always associated 'they' with a multitude of people. You learn something new every day.
