Usage

What’s the difference between uncharted and unchartered? Uncharted means unexplored or unmapped, as in uncharted territory or uncharted waters. 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. 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 uncharted and unchartered 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?

Etymology

Origin of uncharted

First recorded in 1840–50; un- ¹ + chart + -ed ²

Explanation

If a place is uncharted, it means it isn't found on any map, like the uncharted wilderness settlers found when heading west, or, more figuratively — the uncharted territory of a new strategy. The word charted originated in the 1570s, when chart was the name navigators used for maps. So when navigators reached a place not found on their charts, they called the place uncharted. Uncharted also can be used in a figurative sense to describe the start of a new experience, such as the uncharted territory of talking about a difficult subject for the first time.
