Reply To: Are you makpid on ע ?

Akuperma is right, except that literary Hebrew never died, but spoken Hebrew did. (a trivial point, it is pronunciation).
I’ll add to Akuperma’s list the letters that Ashkenazim pronounce differently than North Africans and Middle Easterners.
The Gimel, Vav, Tet, Samech, Tzadi (k), Kuf, Resh, Sin, and Tav.
So the OP’s question is misleading, it’s not only the Ayin.
