How is the conjugation for the "vos" pronoun in forms beyond the present indicative?

Question

How is vos (the Argentine pronoun) conjugated in forms beyond the present indicative? Would it be the same as the vosotros forms, except that the i is omitted?

For example:

Vos comprastes; Vos bebistes; Vos vivistes

And if this is the case, does this apply to all other tenses/aspects/moods and their conjugations?

Answer 1

In Argentina, the pronoun is normally conjugated identically to the tú form in all forms except for the present indicative (-ás, -és, -ís) and the imperative (-á, -é, -í), although it may popularly used with other conjugations.

Note that the pronoun is not exclusive to Argentina by any means, and you can find quite a few different forms depending on where you are at. Chile tends to have the most unique forms, some places are more conservative (Venezuela, Cuba) and retain forms that perfectly coincide with the vos reverencial (which is the same as modern day vosotros/as in Spain and Equatorial Guinea), and all feature some degree of overlap between tú and vos forms.
