Hey Harmony, there's more than one way to recognize the spanish in spain and the spanish in southamerica. Talking about pronunciation, in spain they pronounce the “z" with a stronger accent, while here in southamerica, the pronunciation of the “z" is very similar to "s" Talking about grammar, I can say that in segunda persona plural they use vosotros and vosotras, while in southamerica we only use ustedes. I hope that it was helpful. My best wishes for your language learning journey ❤️
