Frequently Asked Questions
Why is lay vs lie so confusing?
The past tense of 'lie' (to recline) is 'lay,' which is identical to the present tense of 'lay' (to place). This overlap is the main source of confusion.
What about 'lie' meaning to tell an untruth?
When 'lie' means to say something false, its conjugation is different: lie, lied, lied, lying. This does not overlap with lay/lie for reclining.
Is 'Now I lay me down to sleep' correct?
Yes. In this prayer, 'I' is laying 'me' down. 'Me' is the direct object, so 'lay' is correct. The subject is performing the action on an object (themselves).
