How To Use “Lay” vs. “Lie” Correctly Every Time

The difference between the verbs lay and lie is one of English’s most confusing questions. Both words involve something or someone in a horizontal position, but where the two words differ has to do with who or what is horizontal—the subject of the verb (the one doing the action) or the direct object (the person or thing being acted upon).

In this article, we’ll break down the difference between lay and lie, including the past tense forms and the phrases lay down, lie down, and laid down.

Quick summary

Lay means to place or put (Lay that here). The word lay is also the past tense form of the sense of lie that means to recline, as in I lay in bed yesterday. Lay down can mean to place down (Lay down your bags), but it can also be the past tense of lie down, as in I lay down for a few hours. A nonstandard but common use of lay is to mean the same thing as the present tense of lie, as in I just want to lay in bed for a few more minutes or I laid down for a few hours. It’s best to avoid this use (and the confusion it can cause) in formal contexts.

Is it lay or lie?

Lay commonly means to put or place someone or something down, as in Lay the bags on the table or I’m going to lay the baby in the crib. It’s a transitive verb, meaning it requires a direct object (I lay the quilt on the couch; I lay the book on the table).

The sense of lie that’s often confused with lay means to be in or get into a reclining position—to recline, as in I just want to lie in bed for a few more minutes. Lie is an intransitive verb, meaning it does not take a direct object (Don’t just lie there).

Lay is typically used with an object, meaning someone or something is getting laid down by someone. In contrast, lie is something you do yourself without any other recipients of the action.

If you’re the one lying comfortably on your back, you want the verb lie, but if you can replace the verb with place or put (Please place the book on the table), then use the verb lay (Please lay the book on the table).

Though this use is considered nonstandard, lay is commonly used to mean the same thing as this sense of lie, as in I just want to lay in bed for a few more minutes. Although lay and lie are often used interchangeably in casual communication, it’s best to use them in the standard way in more formal contexts.

lay vs. lie in the past tense

The confusion between the two words is largely due to the fact that lay is also the irregular past tense form of this sense of lie, as in I lay in bed yesterday morning wishing I could go back to sleep. (In contrast, when lie is used as a verb meaning to tell an untruth, its past tense is simply lied.) The past tense of lay as in “put or place down” is laid, as in I laid the bags on the table.

The past participle forms of lay and lie (formed with the helping verb have) are also distinct: lay maintains its past form laid, but lie becomes lain, as in I have lain in bed for the past three hours.

The continuous tense (-ing form) of this sense of lie is the same as the untruth sense: lying, as in I am lying in bed right now.
