Confusing verbs
Lie, lay, lain—or lay, laid, laid?
These verbs overlap in spelling because lay is both a base form and the past simple of another verb. The object test separates them.
Lie means rest or recline
The relevant forms are lie–lay–lain. This verb does not put a separate object somewhere. The person or thing named by the subject rests by itself.
Every afternoon, the cat lies by the window.
Yesterday, the cat lay by the window.
The cat has lain there all morning.
The cat is lying there now.
Note the spelling of lying. The final ie changes toy before -ing.
Lay means put something down
The forms are lay–laid–laid. This verb normally needs a direct object: the thing that someone places. You laya book, the keys, or a blanket somewhere.
Please lay the map on the table.
She laid the map there yesterday.
She has laid the map beside the compass.
She is laying the map flat now.
Use the object test
Ask What is being placed?
If the sentence supplies an answer, chooselay. In He laid his phone on the shelf
, his phoneis the object. In He lay on the sofa
, nothing is being placed by the action; the subject rests.
I need to lay down. → I need to lie down.
She lay the baby in the cot. → She laid the baby in the cot.
They have laid on the beach all day. → They have lain on the beach all day.
Why “lay” is the trap
Lay can describe present placement—Lay the coat here
—or past resting—Yesterday I lay here
. Look at the time and the object, not the word alone. After has or have, the difference is clearer: has lain means rested; has laid something means placed it.
A different verb, lie–lied–lied, means say something untrue. Its meaning and regular past forms distinguish it from resting.
