Lay vs Lie: What's the Difference?
Quick answer: Use lay when you put something down (it needs an object), and use lie when you recline or are in a resting position (no object needed).
Definition of "Lay"
"Lay" is a transitive verb meaning to place or put something down. It requires a direct object — you lay something.
Etymology: "Lay" comes from Old English lǣġan and Germanic roots meaning "to place." Its core sense of putting or placing has stayed consistent for centuries.
Definition of "Lie"
"Lie" is an intransitive verb meaning to recline or be in a horizontal or resting position. It does not take a direct object — the subject lies down.
Etymology: "Lie" (to recline) comes from Old English licgan, related to German liegen. It’s unrelated to "lie" meaning "not tell the truth," which has a different origin.
