I have trouble with this sentence. "Reason" is singular and I want to use the present tense, not the past.

Which one is the correct one?

  • The reason lays in the facts
  • The reason lies in the facts

Thanks a lot

Context: this sentence is used as an argument encouraging the other persons to look at the facts as they will provide the reason.

When we look at both sentences, we find that there is no object. So it is clear that we need to use an intransitive verb. As the verb "lay" is a transitive verb (needing an object), which means to put somebody or something down in a particular position, its use in the sentence meant is out of the question because it is neither an intransitive verb nor it has the sense needed for the right sentence.

On the other hand, the verb "lie" is an intransitive verb, which has no object. In addition to its main sense i.e. to put yourself in a flat or horizontal position so that you are not standing or sitting, it also means to exist or to be found that is the right sense needed in the sentence. So it's wrong to say that the reason lays in the facts. Instead, it's right to say that the reason lies in the facts.


You asked for the present tense, and it's easy!

The correct one is...

The reason lies in the facts.

Quick tip is -broadly, the word lay requires a direct object and lie does not. That said, you can lie down on the floor but you lay your laptop on the table.

The things go haywire when it comes to the past tense. Because the past tense of lie is lay!.

If The reason lays in the facts would have continued on, the usage of 'lays' could have been right too. For example:

The reason (for his action) lays in the facts not told.

Other example could be "The Internet lays foundation for a new generation of communication vectors."
