"You eat breakfast."
Translation:Dere spiser frokost.
du = você
dere = vocês
In different regions of the English-speaking world, people use different plural you's (y'all, you guys, you lot, youse, yinz &c), but the only official forms are "you" and possibly "you all". It's inconvenient at times, but usually you can tell if it's singular or plural based on context.
