About the Open Dictionary

What is the Open Dictionary?

The Open Dictionary is Macmillan's crowdsourced dictionary, where people who use the Macmillan Dictionary 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!

What happens after I submit my 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 (usually within seven days), 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, added in 2015.

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

Yes! There is an archive of all the words that people have submitted here. The most recently added ones are on this page.
