## Definition

describes a place or situation that is completely new and has not been mapped or experienced before. You use this when you are doing something for the first time.

For teachers: describes a geographical area not recorded on a map or, figuratively, a situation that is unfamiliar and lacks precedents. Often used to describe innovative or risky ventures.

## Examples

- The ship sailed into uncharted waters.
- The company is entering uncharted territory with its latest move into the renewable energy market.
- Navigating the ethical implications of artificial intelligence feels like exploring uncharted territory, as existing legal frameworks fail to address the rapid pace of technological change.

## Pitfalls

- Not "uncharted territorys" but "uncharted territory" — When used figuratively, 'territory' is often treated as uncountable or part of a fixed singular phrase.

## Usage notes

- Typically used attributively before nouns like 'waters', 'territory', or 'regions'.
