What is the Open Dictionary?

The Open Dictionary is Macmillan's crowdsourced dictionary, where you can suggest new words for us to add. The Open Dictionary started in 2009, and since then more than 3000 new words have been added. About half of these new words have been "promoted" to become full entries in the Macmillan Dictionary.

What kinds of word can I submit to the Open Dictionary?

You can add any word or phrase which you know or which you've heard other people using – as long as it's a genuine word (not an invented one) and it is not already in the dictionary.

How do I submit a word to the Open Dictionary?

If there is a word you would like to add, you can find full instructions (including a helpful diagram) and a submission form here.

What happens after I submit a word?

We will check to see if there is independent evidence showing your word in use. If there is, we will add it to the dictionary, but we won't publish anything which may cause offence. Once your word is in the dictionary, your name will appear with it, like in this word.

Can I see other words that have been added to the Open Dictionary?

Yes! You can see the most recently added words here. And you can browse the complete archive of the Open Dictionary words here.
