Six Punctuation Marks You’ve Never Heard of

Percontation Point

Percontation Point

First proposed by Henry Denham in the 1500s, this is, simply put, a reversed question mark used to show that a question is rhetorical. It hasn’t seen a lot of use since the end of the 1700s, but we think it could have a revival because, when marketing, we ask lots of questions that don’t really need an answer, don’t we?


You may have seen a Hedera in Microsoft Word. Translated from Latin as Ivy, a Hedera is used to separate paragraphs in written documents. If your industry requires you to create a high volume of written content, then a Hedera could be a great way to increase clarity and improve readability.


If you want to ask questions loudly or with excitement, then an interrobang is exactly what you’ve been looking for! This combination of an exclamation mark and a question mark is perfect for writing questions that need a bit more oomph. Do you think that this could change your writing style‽ If you do, be sure to let us know!


While sarcasm is a second language to most, it is often hard to convey when writing down what you’d normally say. This is where the SarcMark, created by Douglas Sak, comes in. Using it after a sentence shows the reader that you were being sarcastic and that they should read that sentence with sarcasm in mind.

Certitude Point

Certitude Point

As an expert in your field, you’ll be certain about a lot. Using a certitude point shows that you back this knowledge up while writing. This punctuation mark looks like an exclamation mark with a line through and is a great way to show conviction in what you’re writing. If you believe in what you write, use a certitude point!

Exclamation and Question Commas

Exclamation Comma

Sometimes, when you’re writing, you ask a question of the audience, but the sentence may not be quite finished. While a question mark is final, a question comma is not. It allows you to ask a question without ending your sentence, giving you more space to continue informing the customer or to answer the question there and then.
