your old dusty OED edition
Nope. That's one of the advantages of the OED. It is updating, continually. Plus, I maintain an online subscription. No dust, my friend. You might do some research on what Lexico really is. Try it. Don't make assumptions. The OED is simply the most scholastic source of knowledge of then English lexicon, comprising over 21,000 pages of word information. Dusty? Maybe some people leave it on the shelf, wasting their money. I USE mine.
Yes, the OED does demonstrate that, over time, some words do change, and that others do not. To date, 'gender' remains as it was defined 800 years ago when first it entered the English lexicon. As I've said, sometimes people will alter what they mean by a word, and that is an unfortunate, dismissive and lazy attitude.
create a new word to men what you say.
