Welcome to English in a Minute from home.

This is a piece of wood.

And sometimes we say this: Knock On Wood.

Jonathan, I entered to a contest to win a new car.

Wow, I hope you win!

Me too, but I have the worst luck in contests.

This time, knock on wood, I will win!

Ooh, are you okay?

"Knocking on wood" is something people do or say for good luck.

People say "knock on wood" to mean they need a little luck to help something happen or not to happen.

And if there is some wood nearby, you can really knock on it.

And that's English in a Minute.
