Usage

What’s the difference between unchartered and uncharted? Unchartered means not having (or not done under) a charter or some other kind of official authorization, as in an unchartered flight. It’s sometimes used to mean unauthorized or lawless, as in unchartered activity. Uncharted means unexplored or unmapped, as in uncharted territory or uncharted waters. The chart in uncharted refers to a map, but charted is not commonly used as an adjective—most people would say mapped. In contrast, both unchartered and chartered (meaning having a charter or officially authorized) are used. The two words are often used in much different contexts, but there are some cases where both could apply. For example, a remote parcel of land may be both uncharted (unmapped) and unchartered (not bound by any official charters or laws). Here’s an example of unchartered and uncharted used correctly in a sentence. Example: The movie is an adventure about a group of teens who take a secret, unchartered flight to explore an uncharted island. Want to learn more?
