Here's a breakdown:
* Mabuhay (Tagalog) translates to Mabilay (Pangasinense) - meaning "Welcome" or "Long Live"
* ang (Tagalog) translates to ya (Pangasinense) - a grammatical article that functions as "the" or "this"
* Pilipinas remains the same in Pangasinense
Therefore, the complete phrase in Pangasinense would be "Mabilay ya Pilipinas".
