Lay vs Lie

Quick Summary

Lay means to put something down (transitive, needs an object): "Lay the book on the table." Lie means to recline (intransitive, no object): "I lie down every afternoon." The confusion comes because the past tense of "lie" is "lay."

Lay and lie are notoriously confused because their forms overlap and their meanings are related to position. The key distinction: lay is transitive (requires an object), while lie is intransitive (no object). Even native speakers struggle with this distinction, as documented in usage studies (Brians, 2013).
