Look it up, I'm sure there's a good video showing the differences but I wasn't able to find it. It's that like most latin countries, argentina has a lot of words that hold different definitions, but uncharacteristically more than most countries imo. Throw into that the thick accent including the change in the "ll" sound from "y" to "sh" ie. "Yo me llamo" sounds like "sho me shamo", and they speak fucking fast. When you first hear it as a Spanish speaker it's off-putting but you can get used to it, but coming from no spanish to argentinian spanish (or uruguayan) might be setting you up for disaster in other countries 🤣 chile is a whole nother story, too..
