Here's a breakdown:
* Magandang: Good
* Araw: Day
* Po: A polite marker, used when addressing someone older or as a sign of respect
Other ways to say hello:
* "Kumusta ka?" (pronounced koo-moos-ta ka) - "How are you?"
* "Hello" - This is also widely understood.
* "Magandang hapon" (pronounced mah-gan-dang ha-pon) - "Good afternoon."
* "Magandang gabi" (pronounced mah-gan-dang ga-bi) - "Good evening."
It's important to note that Filipino greetings often include a "po" or "opo" (yes) at the end to show respect.
