Modern Hebrew functions structurally as revived Yiddish in new vocabulary

Evidence

But the transformation of Hebrew from a learned and liturgical language into a living, modern language, while yet retaining a distinctively Jewish character, was the achievement of people who came with a distinctively Jewish language of their own—Yiddish. In a very real sense modern Hebrew is a reincarnation of Yiddish—the same soul in a new lexical body. — Bernard Lewis, From Babel to Dragomans, 957

• DEFINE: Explains how a liturgical language was vernacularized by Yiddish speakers.
• SEED: Could be an essay angle on how revived/traditional languages are always shaped by the mother tongue of their revivers.
