Lay vs Lie: The Hardest Grammar Rule

Even Native Speakers Get This Wrong

Quick Answer

Lay = needs an object (lay something down). Lie = no object (recline yourself).

The catch: Past tense of "lie" is "lay." Yesterday I lay down. (Not "lied"—that means telling untruths!)

When to Use "Lay" (Needs Object)

Lay is transitive—it needs an object (you lay SOMETHING).

  • Lay the book on the table. → book = object ✓
  • I'll lay my cards on the table. → cards = object ✓
  • Hens lay eggs. → eggs = object ✓
  • Please lay the baby in the crib. → baby = object ✓
  • Lay the foundation. → foundation = object ✓

When to Use "Lie" (No Object)

Lie is intransitive—no object needed (you lie down).

  • I need to lie down. → no object ✓
  • The cat lies on the couch. → no object ✓
  • The town lies in the valley. → no object ✓
  • Don't just lie there! → no object ✓
  • Let sleeping dogs lie. → no object ✓

The Conjugation Chart (This Is Why It's Confusing)

Common Mistakes & How to Avoid Them

❌ Incorrect:

"I'm going to lay down."

✓ Correct:

"I'm going to lie down."

Why? No object—you're reclining yourself, not laying something.
❌ Incorrect:

"I laid in bed all day." (for reclining)

✓ Correct:

"I lay in bed all day."

Why? Past tense of "lie" is "lay." You were reclining (no object).
❌ Incorrect:

"Lie the book on the table."

✓ Correct:

"Lay the book on the table."

Why? "Book" is the object—use "lay."
❌ Incorrect:

"The dog is laying on the carpet."

✓ Correct:

"The dog is lying on the carpet."

Why? The dog is reclining (no object)—use "lying."

Frequently Asked Questions

What about "lie" meaning to tell untruths?

That's a different verb! Lie (untruth): lie → lied → lied. Lie (recline): lie → lay → lain.

Is "lay down" ever correct?

Only with an object: "Lay down your weapons." But "I'm going to lay down" (for sleeping) is technically incorrect.

Does anyone get this right?

Honestly? Many native speakers mix these up. In casual speech, "lay down" for reclining is very common (though technically incorrect).
