Lay is often used where lie is considered standard, as in "I'm going to lay down for a quick nap." The use, which dates to the 14th century, troubled no one until the 18th, but since then, people who care about such things have tried to teach the rest of us that a person lies, not lays, down. Lay in the related use means "to place (someone or something) down gently in a flat position." It requires an object; there must be a thing or person being placed.
Lay it down.
It's time to lay the baby down for a nap.
Lie, on the other hand, does not require an object; instead, the one lying down is already in position or is moving or going to move to such a position on their own.
The cat lies there every morning.
You can lie down on the sofa.
The tenses of the verbs complicate things further. Lay becomes laid and laying
