Here's a breakdown:
* Nakaratay: This is a more informal and colloquial way of saying "lying down." It's often used to describe someone who is sick or injured and has to lie down.
* Nakahiga: This is the more formal and standard way of saying "lying down."
So, while "nakaratay" and "nakahiga" both mean "lying down", "nakahiga" is more widely used and understood in formal settings.
