Meet here is shorthand the comment author is using for: https://en.wikipedia.org/wiki/Join_and_meet

You should read it as: "the largest group of properties that both languages agree about said abstractly defined mathematical object."

chuckle thanks for this heroic effort to charitably interpret me as actually being able to type in a coherent sentence :-)

But, alas, I was just trying to type in "meta" and it was auto-completed to "meet". I really, really, hate autocomplete.

sigh I really hate autocorrect. It was supposed to be "meta", not "meet".

It's bad enough that most of the content I read these days is being generated by LLMs. Slowly and inexorably, even the content I write is being written and overwritten by LLMs.
