How to Conjugate Vos
See also Spanish Grammar
In Argentina and some other Latin American countries, people use the pronoun vos in place of tú.
Vos is not the same as vosotros (which is used in Spain). In grammatical terms, vos is an informal second-person singular pronoun. Vosotros is an informal second-person plural pronoun.
More simply, vos replaces tú (in Argentina, Uruguay, etc.) while vosotros replaces ustedes (in informal conversation in Spain).
For example, in Argentina you will be asked the question “¿De dónde sos (vos)? instead of “¿De dónde eres (tú)?”. Both questions mean “Where are you from?” The difference is that the first one uses vos and the second uses tú.
The use of vos is called voseo.
