You write a sentence. You pause. You ask yourself, “Is it sneaked or snuck?”
Many writers stop here. Students stop here. Even editors stop here.
Both words appear in books, news, and daily speech. So people feel unsure. One looks more “proper.” The other sounds more natural. As a result, writers guess. Sometimes they guess wrong.
This confusion happens because English changed over time. Also, American and British habits are not the same. So learners and even native speakers feel stuck between two correct words.
In this guide, you will learn the real difference. You will see where each word fits. You will also learn one easy rule that removes all doubt when you write.
Sneaked or Snuck – Quick Answer
Both are correct past tense of “sneak.”
“Sneaked” is older and more traditional.
“Snuck” is newer and common in American English.
Use sneaked in formal or British writing.
Use snuck in casual American writing.
Example:
- She sneaked out of the room. ✅ (formal, traditional)
- He snuck into the house. ✅ (casual, American)
Easy rule:
If it sounds formal → sneaked. If it sounds casual → snuck.
The Origin of Sneaked or Snuck
The verb “sneak” first appeared in English hundreds of years ago. At that time, the correct past tense was sneaked. People used it in books, letters, and speech.
However, language changes because people speak in faster and easier ways. Over time, many English verbs formed new past tense shapes. For example:
stick → stuck
strike → struck
So people began to say snuck instead of sneaked. It sounded shorter. It felt smoother in speech. Soon, it spread across America.
However, teachers and editors did not accept it at first. They said only sneaked was correct. Meanwhile, people kept saying snuck in daily life. As a result, both forms survived.
Today, dictionaries accept both. Yet the feeling of “which is right” still confuses writers.
British English vs American English Spelling
This difference mostly follows location and tone.
| Region | Preferred Form | Example |
| American English | snuck (common) | He snuck past the guard. |
| British English | sneaked (preferred) | He sneaked past the guard. |
| Formal writing | sneaked | The boy sneaked out quietly. |
| Casual speech | snuck | She snuck into the party. |
In contrast, British publications still favor sneaked. Meanwhile, American news and novels often use snuck in dialogue and storytelling.
So the choice is not about right or wrong. It is about style and audience.
Which Spelling Should You Use?
Your reader decides this.
For US readers: “snuck” feels natural and modern.
For UK and Commonwealth readers: “sneaked” feels correct.
For academic, business, or formal writing: use “sneaked.”
For stories, blogs, or casual tone: “snuck” fits well.
If you write for a global audience, sneaked is the safest choice because nobody sees it as wrong.
Common Mistakes with Sneaked or Snuck
Writers often mix tone and context.
❌ He snuck out of the meeting unnoticed. (formal report)

❌ The thief sneaked into the house. (casual story, American tone)
✅ The thief snuck into the house.
❌ She has snuck into the room before.
✅ She has sneaked into the room before.
Notice the last example. The past participle form almost always stays sneaked in careful writing.
