Lay vs Lie: Which Word Is Correct and When to Use It?

Lay vs Lie is easier to understand when you focus on the action. Lay means to put a person or thing somewhere, so it normally has something receiving the action. Lie means to rest or stay in a position. The subject does this itself. Their past forms cause most of the confusion, so learning those forms is important too.

Here are two simple examples:

Please lay the newspaper on the table.
I want to lie on the sofa.

In the first sentence, someone puts the newspaper somewhere.

In the second sentence, a person rests on the sofa.

That is the main difference.

The Simple Rule Behind Lay vs Lie

A useful way to choose the correct word is to look for the thing receiving the action.

Use lay when you put something somewhere.

Lay the spoon beside the plate.
She lays her coat across the chair.
He laid the package near the front door.

In every sentence, something is being placed.

What did she lay?

Her coat.

What did he lay?

The package.

Now look at lie.

Use lie when someone or something rests, stays, or is located in a place.

I lie on the floor when I stretch.
The puppy lies beside my shoes.
A small cabin lies near the lake.

Nothing is being placed by another person.

A quick memory trick is:

Lay = put something

Lie = rest or stay

Why Lay vs Lie Feels So Difficult

The basic meaning is not the hardest part. The verb forms create the real problem.

For easy understanding between Lay vs Lie: Look at this chart:

Meaning	Present	Past	Past Participle	-ing Form
Put something somewhere	lay	laid	laid	laying
Rest or stay in a position	lie	lay	lain	lying

Notice something unusual.

The word lay is:

the present form of lay
the past form of lie

For example:

Today I lie on the grass.
Yesterday I lay on the grass.

But:

Today I lay the towel on the grass.
Yesterday I laid the towel on the grass.

This is why the two verbs are often mixed up.

When to Use “Lay”

Use lay when a person puts someone or something in a place or position.

It usually needs an object after it.

For example:

Please lay the cards on the desk.
I always lay my watch beside the lamp at night.
She laid the baby softly in the crib.
We have laid the tools near the garage door.

The bold words after the verb receive the action.

A useful test is to ask:

Lay what?

If you can easily answer that question, lay may be the word you need.

For example:

Lay what? The cards
Lay what? My watch
Lay what? The baby

Present Form of Lay

Use lay with I, you, we, and they.

Use lays with he, she, or it.

I lay my school bag beside my desk.

Dad lays his keys near the door.

Past Form of Lay

The past form is laid.

I laid my phone beside the charger.
Ben laid the blanket over the chair.
The teacher laid the worksheets on each desk.

Do not write layed for this meaning.

The correct form is laid.

Past Participle of Lay

Use laid after has, have, or had.

The -ing Form

The -ing form is laying.

When to Use “Lie”

Use lie when a person, animal, or thing rests or remains in a position.

It does not need another object to receive the action.

For example:

I like to lie near the window and read.
The dog lies under the kitchen table.
Your notebook is lying on the floor.
The old bridge lies beyond the village.

In these examples, nothing is being put somewhere.

The subject itself is resting or staying in that place.

Present Form of Lie

Use lie with I, you, we, and they.

Use lies with he, she, or it.

I lie on my back when I rest.
We lie on the grass after lunch.

A narrow road lies behind the school.

Past Form of Lie

The past form is lay.

Yes, this is the strange part.

In these sentences, lay does not mean “put something down.”

It is simply the past form of lie.

Past Participle of Lie

The past participle is lain.

Use it after has, have, or had.

She has lain in bed since the morning began.
The old book had lain in the drawer for years.

You may not hear lain very often in casual speech, but it is the standard form.

The -ing Form

The -ing form is lying.

Several boxes were lying near the wall.

The spelling is lying, not lieing.

One Question Can Help You Pick the Right Verb

When you are stuck between the two words, ask:

Am I putting something somewhere?

If yes, use a form of lay.

Lay your pencil here.
She laid her purse beside me.
They have laid the papers on the counter.

If no, ask:

Is someone or something resting or staying somewhere?

If yes, use a form of lie.

Lie on the bed.
He lay on the carpet yesterday.
The dog has lain there all afternoon.

This simple test solves many Lay vs Lie mistakes.

Lay Down or Lie Down?

Both forms may be correct, depending on how they are used.

Use lie down when the person or animal is going to rest.

I need to lie down after lunch.
Please lie down and close your eyes.
The puppy went to lie down near its bed.

Use lay down when someone puts something down.

Lay down the pencil when you finish.
She laid down the box carefully.
He laid the sleeping child down on the bed.

The main idea stays the same.

Lie down means the subject rests.

Lay something down means the subject puts something in a place.

You may hear people say:

“I need to lay down.”

This is common in informal speech in some places. However, in standard edited English, I need to lie down is the usual form when you mean “I need to rest.”
