The question that has caused otherwise intelligent adults to stare blankly at the ceiling:
Is it “lie down” or “lay down”?
To settle the matter, we spoke with Doug Chernoff who is an experienced English teacher who has spent years teaching everything from intensive academic English to IELTS preparation.
He has seen students survive complicated grammar structures, academic essays, speaking exams and the emotional trauma of the passive voice.
But there is one grammar problem that keeps coming back.
“Lie down or lay down?” he said. “Honestly, this one has been causing unnecessary suffering for generations.”
So we sat down.
Or perhaps we lay down.
We immediately regretted both choices.
Q: Let’s start with the obvious question. Is it “lie down” or “lay down”?
Doug Chernoff: If you mean that you are going to recline yourself, the standard form is “lie down.”
For example:
“I’m tired. I’m going to lie down.”
You are the person doing the lying. You are not putting an object somewhere.
“Lay down” normally needs an object.
“Lay the book down.”
“Lay the baby down.”
“Lay the keys down.”
So if you tell your friend, “I’m going to lay down,” I know what you mean. I also know that English grammar has just quietly left the room.
Q: But people say “I’m going to lay down” all the time.
Doug Chernoff: Absolutely.
And people also say “irregardless.”
The existence of something in everyday speech does not automatically make it the standard form.
Language is messy. English especially enjoys giving us rules and then immediately creating exceptions just to see whether we are paying attention.
Q: Why is this particular mistake so common?
Doug Chernoff: Because English decided that one verb was not enough.
We have lie, lay, and lain.
Then we have lay, laid, and laid.
And just for fun, the past tense of “lie” is “lay.”
So:
- Present: lie
- Past: lay
- Past participle: lain
Then:
- Present: lay
- Past: laid
- Past participle: laid
That is the kind of system you design when you want English learners to question their life choices.
Q: So “I lay down yesterday” is correct?
Doug Chernoff: Yes.
And this is where everyone starts throwing grammar books at me.
If you are talking about the past, “I lay down yesterday” is correct.
For example:
“I lay down for an hour yesterday.”
But if you are talking about now or the future:
“I lie down every afternoon.”
“I’m going to lie down.”
This is where people get confused because lay is the past tense of lie.
English has decided that the correct answer should sometimes look exactly like the incorrect answer.
Very considerate of English.
Q: What about “I have lain down”?
Doug Chernoff: Correct.
But congratulations. You have now entered the part of English where most native speakers would rather change the sentence.
“I have lain down” is grammatically correct, but in ordinary conversation people often say something like:
“I’ve been lying down.”
Or simply:
“I was lying down.”
There is nothing wrong with “lain.” It just has a rather formal personality.
Q: Can you give us the easiest way to remember the difference?
Doug Chernoff: Think about whether there is an object.
If you are reclining yourself, use lie.
“I need to lie down.”
If you are putting something somewhere, use lay.
“Lay the phone down.”
You lie down.
You lay something down.
That is the basic distinction.
Q: What about “lay down and relax”?
Doug Chernoff: That depends on what exactly you mean.
If you’re giving someone an instruction to recline, standard English would traditionally use:
“Lie down and relax.”
But “lay down” is extremely common in informal speech, particularly in some varieties of English.
This is one of those situations where grammar, dialect, history and actual human speech all decide to have a meeting without inviting the learner.
Q: Is “lay down” always wrong when there is no object?
Doug Chernoff: No. That’s an important distinction.
It can be correct if “lay” is the past tense of “lie.”
For example:
“Yesterday, I lay down on the sofa.”
That’s perfectly fine.
The problem is using lay as the present-tense verb for reclining:
“I’m going to lay down.”
In standard English, that’s usually “I’m going to lie down.”
Q: So when someone says “I’m going to lay down,” should we correct them?
Doug Chernoff: Please don’t sprint across the room waving a dictionary.
If you’re an English teacher, perhaps you have a professional obligation to notice it.
If you’re their friend, you probably have a professional obligation to let them finish their nap.
Not every grammatical mistake needs to become a courtroom proceeding.
Q: Does this matter in IELTS?
Doug Chernoff: It can, particularly if you’re being assessed for grammatical accuracy.
In an IELTS speaking test, you don’t want to deliberately use an incorrect form when you know the standard form.
But I wouldn’t spend your entire preparation time worrying about lie and lay.
If you’re struggling to organize your ideas, develop answers or communicate clearly, those issues are much more important.
Grammar matters. Communication matters more.
Q: What would you say to someone who insists that “lay down” is correct because everyone says it?
Doug Chernoff: I’d say they’re making a perfectly understandable observation about language.
I’d also say that “everyone says it” is not a particularly reliable grammar textbook.
English changes because people use it.
But there is still a difference between what is common in informal speech and what is considered standard in formal English.
Both are worth understanding.
Q: What is the funniest lie-and-lay mistake you’ve encountered?
Doug Chernoff: The classic situation is when someone is telling a story in the past.
They say:
“I was so tired that I lay down.”
Then five minutes later:
“Then I laid there for two hours.”
Now we’ve gone from grammar lesson to crime scene.
The speaker has successfully used two different verbs while trying to describe the same horizontal position.
Q: Can you give us a quick cheat sheet?
Doug Chernoff: Absolutely.
Lie = recline yourself
“I lie down after lunch.”
Lay = put something somewhere
“I lay the book on the table.”
Lay = past tense of lie
“Yesterday, I lay down for an hour.”
Lain = past participle of lie
“I have lain there long enough.”
Laid = past and past participle of lay
“I laid the book on the table.”
And if you remember only one thing, remember this:
You lie down. You lay something down.
Q: And if we’re still confused?
Doug Chernoff: Change the sentence.
This is something experienced English users do all the time.
Instead of:
“I am going to lie down.”
You can say:
“I’m going to rest.”
Instead of:
“I lay down yesterday.”
You can say:
“I rested yesterday.”
You don’t have to wrestle a grammatical bear every time you want to take a nap.
Q: Final question. Why has English made “lie” and “lay” so unnecessarily complicated?
Doug Chernoff: Because English has been collecting vocabulary from other languages for centuries, changing pronunciation, dropping old forms, keeping irregular verbs and generally refusing to clean its room.
And yet we love it.
That’s the strange thing about English.
It can give you twelve ways to misunderstand a sentence, five pronunciations for the same letters and a verb whose past tense looks like another verb.
Then it expects you to teach it to international students.
Honestly, that’s the real IELTS test.
The Verdict
If you’re reclining yourself, say:
“I’m going to lie down.”
If you’re putting something somewhere, say:
“I’m going to lay the book down.”
If you’re talking about yesterday:
“I lay down.”
And if you’ve been staring at this article for twenty minutes trying to remember which one is which, there’s only one grammatically safe conclusion:
Lie down.
You’ve earned it.
Just don’t lay yourself down.
English has already suffered enough.
