Introduction
Many English learners feel confused when they see both “sneaked” and “snuck” used as the past tense of the verb sneak. Which one is correct? Are they interchangeable? Is one more formal than the other?
This topic matters because using the correct verb form helps you sound natural and confident in English. In writing—especially academic or professional writing—choosing the right form can also affect how formal or polished your work appears. In this article, you will learn the difference between “sneaked” and “snuck,” when to use each one, and which form is preferred in different situations.
What Does “Sneak” Mean?
The verb “sneak” means to move quietly or secretly, usually to avoid being noticed.

It can also mean doing something secretly or without permission.

The confusion begins when we change “sneak” into the past tense.
The Two Past Tense Forms: “Sneaked” and “Snuck”
1. Sneaked
“Sneaked” is the traditional and older past tense form of “sneak.” It follows the regular pattern of adding -ed to the base verb.

For many years, “sneaked” was the only accepted past tense form in formal English.
2. Snuck
“Snuck” is an irregular past tense form. It became popular in American English during the 19th century and is now widely used in everyday conversation.

Although some people once considered “snuck” incorrect, it is now accepted in standard English, especially in informal contexts.

Why Does “Snuck” Exist?
English sometimes creates irregular forms by analogy. For example:
- Stick → Stuck
- Strike → Struck
Because “stick” becomes “stuck,” many speakers began forming “snuck” from “sneak.” Over time, this form became widely accepted.
Language naturally changes, and “snuck” is an example of how spoken English influences grammar.
Common Mistakes to Avoid

Avoid incorrect combinations such as:
❌ He has snuckED into the room.
The correct forms are:

2. Thinking “Snuck” Is Always Wrong
Some learners believe “snuck” is incorrect. This is not true. Modern dictionaries accept “snuck” as a standard past tense, especially in American English.
