Keep reading to learn more about “shalln’t” and “shan’t” as contractions. We’ve explained more about them and how you can use them.


“Shan’t” is the correct way to contract “shall not.” When contracting the phrase, you should remove the “l” letters and pronounce it with a longer “a” sound.

The definition of “shan’t,” according to The Cambridge Dictionary, is “short form of shall not.”

However, “shall not” is not common in modern English. People see “shall” as too posh for most writers and speakers. Therefore, it’s left out of most people’s vocabulary.

Nevertheless, it’s still grammatical and correct. It’s quite formal, too, so people tend to use it more in professional situations.

Here are some examples showing you how to use it:

  • You shan’t get away with this again, Julien. I’m going to bring you down for this.
  • She shan’t hear the last of it. Though, we aren’t sure how to contact her.


“Shalln’t” is an archaic contraction of “shall not.” It’s never used today, meaning you should avoid using it yourself.

It is not a word recognized by any official dictionaries. While some natives will understand what you’re trying to say, you should avoid using it to show you understand that it’s not correct.

Instead of “shalln’t,” you might be better off with “shouldn’t.” It’s a more effective contraction, and many people prefer using it.

So, here are some examples demonstrating the different forms:

  • Correct: You shouldn’t be doing this. It’s not going to work well.
  • Incorrect: I shalln’t say another word since I’m afraid of what might happen.


You should only use “shan’t.” It’s the correct contraction for “shall not,” making it the only useful term here.

“Shalln’t” was once correct, but it is archaic today. Therefore, it has no purpose in modern English.
