Quick answer: You use “lying down” when a person or animal reclines on their own, and “laying down” only when you are placing an object onto a surface. If you are putting yourself to bed, you are lying down.
As a veteran copy editor who has spent over fifteen years correcting manuscripts, corporate communications, and self-published novels, I see the “laying down or lying down” mistake more than almost any other verb confusion. Even seasoned writers trip over these two words because their past tenses overlap, creating a grammatical minefield. Let’s clear up the rules once and for all so you never second-guess yourself when drafting your next email or manuscript.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| Laying down | Placing an object onto a surface (requires a direct object). | I am laying down the new tile in the kitchen. |
| Lying down | Reclining or resting your own body (does not take a direct object). | I am lying down on the couch for a quick nap. |
When to use laying down
“Laying down” is the present participle of the transitive verb “lay.” A transitive verb strictly requires a direct object to receive the action. You cannot just “lay.” You must lay something. The subject is performing an action upon an object, moving it from one place to a resting position.
I once edited a DIY home renovation blog where the author repeatedly wrote, “I am laying down on the couch after painting the walls.” I had to explain that unless she was physically placing her body onto the cushions like a throw pillow, she was lying down. However, later in the same post, she correctly wrote, “I am laying down a fresh coat of primer.” Here, the “fresh coat of primer” acts as the direct object. Recognizing the direct object is the absolute key to mastering this transitive verb.
Here are a few more correct, real-world examples of “laying down”:
- Text to a spouse: “I’m laying down the baby in the crib, call you in five.” (The baby is the object).
- Wedding Toast: “We are laying down a foundation of love and trust today.” (A foundation is the object).
- Construction Email: “The crew is laying down the concrete for the new patio.” (The concrete is the object).
This physical act of intentionally placing something is deeply rooted in historical and physical actions. Consider the religious ritual of the laying on of hands, where a person deliberately places their hands upon another to confer a blessing, healing, or ordination. Both actions are transitive; they require a direct object receiving the physical placement. If you remove the object from the sentence, the grammar completely collapses.
When to use lying down
“Lying down” is the present participle of the intransitive verb “lie.” Intransitive verbs do not take a direct object. The subject is performing the action on themselves, reclining or resting their own body.
Last month, I reviewed a cover letter for a senior copywriter position. The applicant wrote, “After a long day of writing, I enjoy laying down on the sofa.” I immediately passed on the candidate. If a professional writer cannot master the present participle of their own physical state, I cannot trust them with my client’s prose. The correct sentence is, “After a long day of writing, I enjoy lying down on the sofa.”
Here are correct, real-world examples of “lying down”:
- Sick day text to a boss: “I have a severe migraine and am lying down in the dark room. I will be offline for the afternoon.” (No object).
- Novel excerpt: “Exhausted from the hike, she was lying down on the mossy bank when she heard the branch snap.” (No object).
- Journal entry: “I spent the entire Sunday just lying down on the couch, watching old movies.” (No object).
Be careful not to confuse the physical act of reclining with the deception of telling a falsehood. As noted in the etymological breakdown of lying, the verb for speaking untruths shares the exact same present participle spelling as reclining. This means a sentence like “He is lying down” could theoretically mean he is telling a falsehood while pointing at the floor, though context makes this absurd. Still, context is your only guide in written English to separate a person resting their eyes from a person deceiving their friends, and mastering the physical verb ensures your prose remains unambiguous.
How to remember the difference
When you are staring at a blinking cursor and cannot decide between “laying down or lying down,” rely on the substitution trick. Replace the verb in your sentence with the word “place” or “put.”
- “I am [placing] down on the bed.” This makes no sense. Therefore, you must use “lying.” (I am lying down on the bed).
- “I am [placing] the book down on the table.” This makes perfect sense. Therefore, you must use “laying.” (I am laying the book down on the table).
If the substitution trick fails you, use the letter association mnemonic.
- pLace = Lay. Both words contain the letters L and A. When you are placing an object, you use “lay.”
- rEcLInE = Lie. Both words contain the letters L, I, and E. When you are reclining your body, you use “lie.”
Another editor-level trick is to think about chickens. A chicken lays eggs. The egg is the direct object. The chicken cannot just “lie” an egg, because that would mean the chicken is reclining and an egg magically appears. Because “lay” always requires an object (the egg), you can remember that “laying” always requires an object. You are not a chicken, and you are not producing an egg, so you are not “laying down” unless you are holding something in your hands and placing it onto a surface.
Common mistakes and exceptions
The present participle (“laying” vs “lying”) is only half the battle. The real reason “laying down or lying down” causes so much grief is the past tense trap. This is where ninety percent of errors happen in published books and professional emails.
The past tense of the intransitive verb “lie” is “lay.” The past tense of the transitive verb “lay” is “laid.”
Because the past tense of “lie” is identical to the present tense of “lay,” our brains short-circuit. Here is the complete conjugation chart you need to memorize:
- Present: I lie down / I lay the book down.
- Past: I lay down / I laid the book down.
- Past Participle: I have lain down / I have laid the book down.
- Present Participle: I am lying down / I am laying the book down.
Look at this common mistake: “Yesterday, I laid down for a nap at 2 PM.” This is grammatically incorrect, yet you will hear it in casual conversation constantly. The correct phrasing is, “Yesterday, I lay down for a nap at 2 PM.” It sounds strange to modern ears because we rarely use “lain” or the past tense “lay” for reclining in spoken English, but in formal writing, “laid down” requires an object. “Yesterday, I laid the baby down for a nap” is perfectly correct.
The past participle “lain” is practically extinct in modern casual speech, which is why writers default to “laid.” Consider the sentence: “The treasure has laid hidden for a century.” This is incorrect. The treasure did not place anything; it simply rested. The correct phrasing is, “The treasure has lain hidden for a century.” Similarly, if you write a suspense novel and your protagonist says, “I have laid in wait for three hours,” your editor will immediately flag it. The protagonist has not placed an object; they have reclined or rested in wait. The correct dialogue is, “I have lain in wait for three hours.”
There are a few idiomatic exceptions where “lay” is used without a physical object, but these are fixed phrases. You can “lay down the law,” “lay down your arms,” or “lay down a track” (in music production). These are established metaphors for placing rules, weapons, or audio recordings onto a metaphorical surface.
Frequently Asked Questions
Is it “laying in bed” or “lying in bed”? It is “lying in bed” unless you are placing something else into the bed, like a dog or a hot water bottle. If you are the one resting under the covers, you are lying in bed.
What is the past tense of lying down? The past tense of “lie” is “lay.” So you would correctly say, “Yesterday, I lay down at 9 PM.” This overlap in spelling is exactly why the confusion between these two verbs exists in the first place.

Is “laying down” ever correct without an object? Only in highly informal, colloquial speech. In some regional dialects, “lay” has completely swallowed “lie.” However, in any professional cover letter, published novel, or corporate memo, using “laying down” without a direct object is considered a glaring grammatical error.
