Infamous means being well-known for a negative reason. It's a synonym for "notorious" or "disgraced".
Here's a breakdown:
* Famous means "well-known".
* In- is a prefix meaning "not" or "opposite of".
Therefore, infamous means "not famous", or "famous for something bad".
Example:
* "The infamous pirate Blackbeard was known for his ruthless attacks and terrifying appearance."
It's important to note that while infamous refers to negative notoriety, it doesn't necessarily imply moral judgment. Someone can be infamous for something that might be considered admirable by some, like a revolutionary leader or a whistleblower.
