Meaning

## What it means

As slang, bet confirms an arrangement, approves an idea, or accepts a challenge. It can be sincere, clipped, or lightly playful, and its tone depends on the surrounding conversation. The current form is not an acronym and does not refer to the TV network BET.

See the quick definition in the [bet dictionary entry](https://genzdecoded.com/dictionary/bet/).

Usage

## How to use it

- “Can you send the notes after class? Bet.”

    Confirming that you will do something.

- “Meet at seven? Bet, I’ll be there.”

    Agreeing to a plan.

Origin

## Where it came from

Merriam-Webster traces slang bet to African American English in the 1980s, likely as a shortening of older affirmative expressions such as you bet and you can bet on it. Those older expressions are recorded in American English from the 1850s and build on the ordinary verb bet, meaning to wager.
