The PAST tense of the verb "to lie" (recline)

Context Examples:

Memory Tricks

1. The Object Test

If you can ask "Lay WHAT?" → use LAY
If you can't complete "Lie WHAT?" → use LIE
Example: "Lay the book where?" (has object) vs. "Lie where?" (no object)

2. The "D" Rule

LAy → LAiD (both have "ai")
Lie → Lay → Lain (all start with "L" + vowel)
LAiD and LAying both have "A" - think "A" for "Action" (putting something)

3. The Person/Thing Rule

LAY → you LAY a THING down (thing = object)
LIE → YOU lie down (you = subject, no object)

4. Substitution Test

If you can substitute "place" or "put" → LAY
If you can substitute "recline" → LIE

5. The "Now I" Trick

Now I lay the book down (present tense of lay - has object)
Now I lie down (present tense of lie - no object)
Yesterday I laid the book down (past tense of lay)
Yesterday I lay down (past tense of lie - THIS IS THE TRICKY ONE!)

6. The Chicken Test

Chickens lay eggs (lay WHAT? eggs - has object)
Chickens don't lie eggs (makes no sense)
But: Chickens can lie on their eggs (recline on them - no "what")

7. The "Laying vs Lying" Rule

LAying = putting something down (has object)
Lying = reclining (no object)
"She's laying tile" (putting down tile)
"She's lying down" (reclining)
