What does the Yiddish word yada mean?

The Yiddish word "yada" is actually a shortened form of the Hebrew word "yada'a" (יָדַע), which means "to know" or "to know about."

In Yiddish, it is often used as an interjection similar to "you know" or "and so on" in English. For example:

* "I went to the store, bought some groceries, yada yada, came home."

* "He said he was busy, yada yada, made up an excuse."

It's a casual and informal way to indicate that you're omitting details or summarizing a long story.
