In Filipino/Tagalog, you = "ikaw" (or "ka", depending on the way the sentence is structured) which is okay to use for peers or younger people. For older people or people of higher positions, we address them with the "plural you" = "kayo". We also add "po" when speaking politely/respectfully.

For example:

"Nasaan ka?" = "Where are you?"

"Nasaan po kayo?" = "Where are you?" (respectfully)
