Formal:
* Ikaw ba? (ee-KOW bah?) - This is the most common and formal way to say "are you?"
* Kayo ba? (KAH-yo bah?) - This is the formal plural version, used when addressing multiple people.
Informal:
* Ikaw? (ee-KOW?) - This is a more casual version of "are you?"
* Kayo? (KAH-yo?) - This is the informal plural version, used with friends or family.
In a sentence, you would use these phrases like this:
* Ikaw ba ang nagluluto? (ee-KOW bah ang nag-loo-loo-toh?) - Are you the one cooking?
* Kayo ba ang mga bagong estudyante? (KAH-yo bah ang mga bah-goo-ng es-too-dyan-tay?) - Are you the new students?
It's important to note that Tagalog uses subject-verb-object word order, so the "you" comes first in the sentence.
