Sneaked or Snuck: What Is Actually Correct?
This is where grammar meets real-life language.
The standard form: sneaked
Sneaked follows normal English grammar rules.
Most verbs in English form the past tense by adding -ed:
- walk → walked

- strike → struck
So speakers extended this pattern and created:
- sneak → snuck
