✅ Yesterday, she snuck out of the house.

When talking about a completed past action in an affirmative sentence, use a past form.

✅ Did you sneak out?

After did, use the base form sneak.

Mistake 3: Using “Did Snuck”

❌ Did he snuck into the room?

✅ Did he sneak into the room?

The same rule applies: did + V1.

❌ sneakking

❌ sneeking

✅ sneaking

The correct spelling is sneaking.

Because snuck can also function as a past participle, it can be used after have, has, or had.

❌ She has sneak into the room.

Remember:

have/has/had + past participle
