A meaningless emphasis particle stuck on the end of sentences.
Po carries no meaning at all — it adds punch. "Sí po," "ya po," "no po" are the three you will hear most. Nearly impossible to use wrong and instantly makes you sound Chilean, which is why it is the first thing learners in Santiago pick up.
Worn-down "pues," reduced to a single sound over generations.
Chile and nowhere else. It is the loudest single marker of Chilean Spanish.
Reading a definition isn't the same as saying it to someone. Lingo Kaiava is a voice tutor set to Chilean Spanish — it uses po the way locals do, corrects you in the moment, and never "fixes" the way real people actually talk into textbook Chilean Spanish.
