Put your money where your mouth is~!

Today we'll look at a few idioms linked to gambling. If you are very sure about something you could say:

I'd put money on it.

This means that you believe it so much that you are willing to bet money that you're right. It is generally used in the following grammar structure:

X would put money on Y

And since you are telling people about your high degree of certainty X is usually I.

I'd put money on it raining tomorrow.

I'd put money on Tom getting the promotion.

You might talk about other people but this isn't so common:

She'd put money on him proposing on their anniversary next week.

In this case it is a form of reported speech, you are telling someone that she told you he is sure he will propose on their anniversary.

Another, more dramatic way, to express a high degree of certainty that something is true/will happen is to say:

I'd stake my life on it

You often hear this in casual English and it is in a ton of movies where gangsters catch someone and want them to talk:

Gangster: Where's the money?

John: I don't know~!

Gangster: (breaks a finger) Where's the MONEY?

John: Tom might have it...

Gangster: MIGHT? (pushes on the broken finger)

John: He has it, he has it. I'd stake my life on it.

Gangster: You just did.

In this case you are literally saying "I'd bet my life on it" so if you are wrong they'll kill you!

The last idiom we'll look at is one where two people are arguing and someone says"

Put your money where your mouth is!

This means that you talk tough like you are right or can do something but prove it - make a bet and show me I'm wrong.

Al: I can sink 3 basketballs in 1 minute from half-court.

Bill: What? No way!

Al: I can, I do it all the time.

Bill: Put your money where your mouth is, 20$ says you can't.

Al: You're on, let's go to the basketball court and I'll show you how it's done.

So Al said he could do something, Bill didn't believe him and bet him 20$ he can't. They made a bet and now they will go find out who is right.

Have a nice weekend guys,
