Being "tempted" means that you want to do something even though you know that it's wrong or a bad idea. For example, you might be "tempted" to:
- cheat on a test
- eat some unhealthy food
- drive faster than the speed limit
Here's an example:
Have you ever been tempted to take a little money out of the cash register when no one was looking?
People sometimes say "I'm tempted to ___" to announce something that they're considering doing:
Their service is horrible. I'm tempted to cancel my contract with them.
In this example, the speaker is thinking about canceling a contract, but hasn't definitely decided yet.
