Answer:
For "lay," the past tense is "laid." So, for example, if yesterday you placed a book on the table, you'd say, "I laid the book on the table."
For "lie," the past tense is "lay" as well. It might sound a bit confusing, but it's like this: If you were feeling tired yesterday and decided to rest, you'd say, "I lay down for a nap."
Step-by-step explanation:
So, "laid" is for "lay," and "lay" is for "lie" in the past tense. They sound similar, but they have different meanings and uses. Just remember that "lay" usually involves putting something down, while "lie" is about yourself resting or reclining. Hope this helps!
