Here's a breakdown:
* Sa: This is a preposition that can mean "to," "for," or "in."
* Inyo: This is the possessive form of "kayo" (you, plural).
* Lahat: This means "all."
So, putting it all together, "sa inyong lahat" literally means "to/for you all."
It's a polite and respectful way to address a group of people, often used in speeches, announcements, or greetings.
