Lay vs Lie: Which One Do You Need?
Lay needs an object — you lay something down. Lie does not — you simply lie down.
Lay the book on the table. Go and lie down.
The test that settles it
See whether a thing can follow the verb. If something is being put down, use lay. If a person or thing is settling by itself, use lie.
“___ the tools in the box” → the tools are the object, so lay.
“I need to ___ down” → nothing is being put anywhere, so lie.
pLAce and lAy both take an object; recLIne and lIe do not.
Lay: to put something down
Transitive, meaning it must have an object. Its forms are lay — laid — laid.
Please lay the cloth on the table.
She laid the baby in the cot.
They have laid new carpet upstairs.
Swap in place or put. If it works, lay is right.
Lie: to be in a resting position
Intransitive — it takes no object. Its forms are lie — lay — lain, and that middle form is where the confusion starts.
I am going to lie down for an hour.
The village lies east of the river.
The papers had lain there for weeks.
Swap in recline or be situated. If it works, lie is right.

The exceptions
The past of lie is lay — the same word as the present of the other verb. Yesterday I lay down is correct, and it looks wrong to almost everyone.
I laid down is only correct if you laid something down.
There is a second verb lie, meaning to tell an untruth, and its past is lied. It is unrelated and rarely causes trouble because the meaning is so different.
