Word Choice: Uncharted vs. Unchartered

At first glance, the words ‘uncharted’ and ‘unchartered’ look almost identical. But the pesky extra ‘-er-’ in ‘unchartered’ changes the meaning entirely.

As a result, it is easy to use these terms incorrectly, even if you already have a vague idea of what they each mean! Luckily, we’re here to help.

Uncharted (Unmapped or Unknown)

The word ‘uncharted’ means ‘unexplored’ or ‘unknown’. It can help to remember that a ‘chart’ can be a ‘map’, so ‘uncharted’ means ‘not yet on the map’. This can apply both to physical regions and areas of knowledge.

It would thus be used in a literal sense, like this:

We know little about the uncharted depths of the sea.

Or it could be used in a more metaphorical sense:

Nuclear fission is a largely uncharted area for science.

But this word is always about something unknown.

Unchartered (Without a Charter)

The word ‘unchartered’, meanwhile, is an adjective meaning ‘lacking a charter’. The charter in question is a document which grants rights or authorises someone to work in a specific role. For example:

He ran his business as an unchartered bank.

This means ‘unauthorised’ or ‘lacking regulation’. However, this term is rare in most contexts, so you should not need to use it on a regular basis.

Uncharted Territory

One common error with these terms occurs with the phrase ‘uncharted territory’. This is a figure of speech meaning ‘a new and unknown area’, usually in relation to a field of activity or thought:

Virtual reality is still uncharted territory for many entertainment companies.

As such, ‘uncharted’ is always the right word in this context. Remember:

  • Uncharted territory – Correct
  • Unchartered territory – Incorrect

Uncharted or Unchartered?

Since ‘unchartered’ is so rare, most of the time the word you’ll need is ‘uncharted’. Remember:

  • Uncharted means ‘unknown or unmapped’.
  • Unchartered means ‘without a charter’.

Thank you!! I am constantly hearing "unchartered territory" on news broadcasts, and it was starting to make me doubt my lifelong use of "uncharted territory." I am glad to finally look into this question, and glad I have been using the correct term all along! ; > )

    I was starting to wonder if there was new specifically political usage , where, say, a political actor was operating, with executive privilege far outside customary limits.By denying the power of the most fundamental documents of the nation, he renders all "unchartered" - without a constitution or rule of law! Much more worrying than merely "uncharted"!

Am I the only one who's only heard "uncharted waters" and never "uncharted territory"? BTW I came here after reading on https://abcnews.go.com/Politics/biden-sanders-face-off-debate-democratic-race-coronavirus/story?id=69578638, "The novel coronavirus... thrust the 2020 campaign into unchartered virtual terrain"

    Hi, James. Both phrases are used to mean the same thing, though 'uncharted territory' is becoming more common (e.g. https://books.google.com/ngrams/graph?content=uncharted+waters%2Cuncharted+territory&year_start=1800&year_end=2008&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Cuncharted%20waters%3B%2Cc0%3B.t1%3B%2Cuncharted%20territory%3B%2Cc0). I suppose it depends on whether you're more inclined toward life on land or at sea!

I regard “unchartered” as having a perhaps more intrinsic meaning of “unregulated.” Is that not correct?

    Hi, Sharon. That's not a standard use of 'unchartered' that I've seen listed in any dictionaries, so I'd be cautious about using it in that sense, although I'm sure it has been used like that in places.
