Uruguay. In those countries, it is used by many to address others in all kinds of contexts, often regardless of social status or age, including by cultured/educated speakers and writers, in television, advertisements, and even in translations from other languages. In Guatemala and Uruguay, vos and tú are used concurrently, but vos is much more common. Both pronouns use the verb forms normally associated with vos (vos / tú querés, 'you want'). The name Rioplatense is applied to the dialect of Spanish spoken around the mouth of the Río de la Plata and the lower course of the Paraná River, where vos, not tú, is invariably used, with the vos verb forms (vos tenés). The area comprises the most populous part of Argentina (the provinces of Buenos Aires and Santa Fe) as well as an important part of Uruguay, including Montevideo, the capital. In Ecuador, vos is the most prominent form throughout the Sierra region of the country, though it does coexist with usted and the lesser-used tú.

In the more-populated coastal region, the form tú is used in most situations, usted being used only for unfamiliar and/or superior addressees.Vos can be heard throughout most of Chile, Bolivia, and a small part of Peru as well, but in these places it is regarded as substandard. It is also used as the conversational norm in the Paisa Region and the southwest region of Colombia, in Zulia State (Venezuela), in Honduras, El Salvador, Costa Rica, Guatemala, and the state of Chiapas in Mexico. In Chile, even though tú is the prestige pronoun among educated speakers, the use of "verbal voseo", i.e. "tú + verb
