1. Ó, desculpe! Com licença! – “Excuse me”
You can strike the “com licença” and just say “ó, desculpe!” over and over again until someone hears you. It works everywhere, from asking for help in the streets to ordering food.
2. Pá – “Hey,” “So,” and other meaningless interjections
“Pá” is the Portuguese equivalent of “che” for Argentinians. You use it at the beginning or ending of a sentence. Or you can just say “Pá…” and scratch your head, while thinking about something.
During the Carnation Revolution, a French journalist came to Portugal (without knowing much Portuguese) and, after talking to a lot of people, made a note to see a guy named “Pá” since he was always being mentioned. That’s how much we use it.
