Best practice
Use "lie in" to indicate where the solution to a problem or the cause of a situation can be found. For example, "The answer may lie in further research."
Common error
Avoid using "lay in" when you mean "lie in". "Lay" requires a direct object (e.g., "lay the book down"), while "lie" means to recline or be located. To avoid this, remember that you "lie in" bed, but you "lay something" on the bed.
