These may well be the two most confounding three-letter words in all the language. The use of lay where lie is indicated has been a major problem for generations. To lay is to put or place: I will lay my cards on the table. To lie is to rest or recline: The cards lie on the table. But lie also means "to tell an untruth." Maybe because of the word's negative double meaning, people shy away from saying lie.
All of the following are incorrect: I'm going to lay on the couch. Your wallet is laying on the dresser. He wants to lay down. Make it lie, lying, lie, respectively.
Lie: You lie down today; you lay down yesterday; you have lain down before.
Lay: Please lay the book down now; you laid the book down yesterday; you have laid that book down before.
