What’s the difference between lay and lie?
You lie down, but you lay something down. Lie does not require a direct object. Lay requires a direct object. The same rule applies to laying and lying (not lieing—beware of spelling). The past tense of lay is laid, but be careful with the past tense of lie—there are two options. We’ll dive into them later.
When to Use Lay
To lay is to set (or otherwise place) something in a resting position.
