Well, Merriam-Webster fell into an awkward place.
They tweeted something cutesy and fun:
“What language rule are you willing to die on a hill for?”
Or words to that effect.
They probably hoped for something about split infinitives or ending sentences with prepositions.
Instead, they deleted the tweet after folks came back with:
“Woman” means adult human female.
How radical and controversial…
I’d almost defend the dictionary folks here. Dictionaries merely document language, not police it. If enough folks want to use a word wrong, the dictionary’s job is to document that.
Dictionaries reflect usage.
So it’s not their fault if they’ve noticed a new way of using “men” and “women”.
That’s a reasonable argument.
It falls apart when you realise that it means they have to listen and observe common usage.
Anyway, I think we’ve won here or something, because looking up “man” and “woman” in Merriam-Webster’s site now gives you good definitions:
Woman: (1a): an adult female person
Man: (1a1): an individual human; especially : an adult male human
And none of the definitions talked about identifying as anything.
So I don’t know what those tweets were about. Maybe their social media managers haven’t read a dictionary.
Anyway, here’s a link to something with tight definitions and consistency:
