a nonstandard lower speaking style, whereas in Argentina and Uruguay it is standard. The second person plural pronoun, which is vosotros in Spain, is replaced with ustedes in Rioplatense, as in most other Latin American dialects. While usted is the formal second person singular pronoun, its plural ustedes has a neutral connotation and can be used to address friends and acquaintances as well as in more formal occasions (see T–V distinction). Ustedes takes a grammatically third- person plural verb. As an example, see the conjugation table for the verb amar (to love) in the present tense, indicative mode: Although apparently there is just a stress shift (from amas to amás), the origin of such a stress is the loss of the diphthong of the classical vos inflection from vos amáis to vos amás. This can be better seen with the verb "to be": from vos sois to vos sos. In vowel-alternating verbs like perder and morir, the stress shift also triggers a change of the vowel in the root: For the -ir verbs, the Peninsular vosotros forms end in -ís, so there is no diphthong to simplify, and Rioplatense vos employs the same form: instead of tú vives, vos vivís; instead of tú vienes, vos venís (note the alternation). The imperative forms for vos are identical to the imperative forms in Peninsular but stressing the last syllable: Hablá más fuerte, por favor. "Speak louder, please" (habla in Peninsular) Comé un poco de torta. "Eat some cake" (come in Peninsular) When in Peninsular the imperative has one syllable, a vowel corresponding to the verb's class is added (stress remains the same): Vení para acá. "Come over here" (ven in Peninsular) Hacé lo que te dije. "Do what I told you" (haz in Peninsular) Exceptions to this include: Decime dónde está. "Tell me where it is" (Dime in Peninsular). The second syllable is stressed. The verb ir (to go) is never used in this form. The corresponding form of the verb andar (to walk, to go) substitutes for it. Andá para allá. "Go there" (ve in Peninsular) The plural imperative uses the ustedes form (i. e. the third person plural subjunctive, as corresponding to ellos). As for the subjunctive forms of vos verbs, while they tend to take the tú conjugation, some speakers do use the classical vos conjugation, employing the vosotros form minus the i in the final diphthong.
