Introduction
Few grammar topics confuse writers as much as lay vs lie. Even native English speakers hesitate when choosing the correct word, especially in past tense sentences. These two verbs are often mixed up because they are closely related, sound similar, and overlap in usage but they are not interchangeable.
Lay requires an object you lay something down. Lie, on the other hand, does not take an object you lie down yourself. To make things trickier, the past tense of lie is lay, which adds another layer of confusion.
