"Lay" and "lie" are two of the most commonly confused verbs in English.
Even many native speakers struggle with them.
Both verbs relate to position or placement, but they follow different rules:
Lay is transitive — it requires a direct object (you lay something down).
Lie (to recline) is intransitive — it does not take a direct object.
The confusion increases because the past tense of lie (recline) is lay — the same form as the present tense of lay (place).
