What’s the past tense of “lay”?
Did she lie down or lay down? Did she lie about lying down? Has she lied before? This pair of verb tenses sure is a befuddling grammar puzzle to solve: to lay down vs. lie down, which is correct?

Please lay the blanket over the sleeping child.

“Lay down” or “lie down”?
First understand lie has two meanings as a verb:
1. To lie can refer to someone telling an untruth or false statement. For example, ‘I wouldn’t believe anything she says—she lies all the time.’ The past tense of this meaning of “lie” is lied.
2. Lie also means lie down, or “to assume a horizontal position—often used with down” (which is the sense in which we’re using the verb).
The sentence, ‘I’m going to go lie down for a nap‘ is correct English.
- The past tense of lie is lay, and the past participle is lain.
Here’s the tricky part:
- Lay is also the present tense of the transitive verb meaning to put or place something down (on something). E.g., “we lay down the cement first“.
- The past tense and past participle of lay is laid: ‘She had laid her books on the table before walking over to us‘.
The key difference is that to lie down is intransitive (i.e., it does not use a sentence object). A way to think about the difference is that the action stops and ends with the actor or doer itself: sleeping, for example, is intransitive: sleep is a state of being that begins and ends with us, rather than being done or received by someone or something.
