The words we make can be a window into your life.arrowThink about the parts of your world you’d like others to understand.



First, what type of word would you like to make?

Move the slider below to choose what you’d like your word to describe.

A Negative Experience


A Positive Experience


OK, now we need a base word.

Think of your base word like the base of a pizza that you can add on to. For now, select a base word from the options below or, if you have something specific in mind, you can skip this step and use a base word of your own.

Click on the word field below to edit your base word directly or to type in your own. Tip: Why not try mixing your base word with another word to change its meaning (like how ‘breakfast’ is mixed with ‘lunch’ to make ‘brunch’)?

You can also change your word’s meaning by adding a beginning or an end.

When you’re happy with your word,
it’s time to define it.


Time to define your word!

You’re submitting your new word to be included in The World’s Rarest Dictionary so, like with other dictionaries, we’ll need a definition to help others understand it. Use the space below to define your word and give an example of how you’d use it in a sentence. Please don’t share confidential information about yourself or others.

Define “

How would you use “” in a sentence?


One last step before you submit…
