What is meant by vauching?

Answer 1

It depends on the context.

1. In the Southwest of England English dialect to vauch means to move fast, so vauching would be moving fast.

2. In the context of Jewish funeral practices it could be Yiddish for "watching" referring to the custom that someone should watch over the body of the deceased before burial. (See "shemira").

3. It is sometimes also a mis-spelling of "vouching".
