Modern Hebrew is also a child of Zionism. It differs significantly from liturgical Hebrew since it has a lot of influences from European languages. If I'm not mistaken, some Jewish communities believe it's also a heresy to use the sacred language of the Scriptures in common speech.
If some comrade has more sources on how Jewish communities view modern Hebrew, I would appreciate it. I don't know a lot of details.
Anyways, I didn't know this. Hope Cornish keeps growing.
