You are watching: Lie in wait or lay in wait
Substituting lay (to place or arrange) for lie (to recline or be situated) is undoubtedly one of the most common usage errors in English. Why? Because, for one thing, the past tense of lie is lay. For another, lie can also mean to fib, and using the word correctly might lead to ambiguity in certain instances, as here: Eric is lying about the house.
Is he lounging around, or telling a fib about the house? Context, of course, would provide the needed clarity, but perhaps to avoid potential confusion, our brains default to the word that, although incorrect, leaves no doubt about the meaning. Who knows? Neurolinguistics is hardly my area of expertise …
Whatever the reasons for the confusion, let’s try to clear it up once and for all.
Remembering which word to use is easiest with the present tense. Lay is a transitive verb, meaning it’s followed by a direct object (i.e., whatever is being placed or arranged, shown here in bold): Will you lay the blanket on the bed?
Lie is intransitive, meaning it doesn’t need a direct object for the sentence to make sense: Maria lies down for 20 minutes every night after work.
An easy way to remember which word to use in the present tense is this:
LAY: to PLACE (share the letter A)
LIE: to RECLINE (share the letter I)
Moving beyond the present tense makes things a little more challenging. Not only is the past tense of lie the same word as the present tense lay, but both the past tense and past participle of lay are laid, and the present participle of lie is the same (i.e., lying) whether you’re talking about reclining or fibbing. What?!! Tense matters indeed.
If that’s too much to keep straight (and it’s nearly impossible for most folks), the following chart might help:

A Place for Everything
If the transitive/intransitive, direct object/no object distinctions make your eyes glaze over, there’s an easier way — and it works for all forms of the verb. Not sure whether to use lie or lay or some variation of either? Substitute the word place (or placed or placing, as appropriate to the context). If the sentence makes sense with some form of place, use the corresponding form of lay. Otherwise, use the appropriate form of lie. Let’s try it out (correct answers in green):
The treasure had
I need the third book in that stack
Julia <laid/lay> her briefcase on her desk. Julia could certainly place her briefcase on her desk, so the past tense of lay is correct.
The ground troops <lay/laid> in waiting for nearly 20 hours before the enemy appeared. You wouldn’t say they placed in waiting, so the past tense of lie is correct.
