The first word pair I would like to focus on is lay and lie.

The “lie versus lay” debate is particularly confusing because of their similar spelling and similar meaning.

Recipe for a Grammatical Disaster!! Not to worry.

The key lies in understanding what the words actually mean.

Lie = to recline; to rest; to stay. (Past form = lay)

I don’t feel well; I might lie down for a few minutes.

Lay = to put or to place (Past form = laid)

You must lay the book on the table.

A Memory Trick:

The Gregg Reference Manual offers a useful tip when trying to decide between lay and lie:

Substitute the word “place” for “lay” or “lie” in the sentence.
If place works, use “lay”.
If place makes the sentence sound funny, the correct word is “lie”.

For example, you would not say “I’m going to ‘place’ down.” You would go lie down.
But, to “‘place’ a pie on the table” works, so you can “lay a pie on the table” too!

Still Confused?
