polarity in Rioplatense Spanish

Rioplatense Spanish leaves the positive value unmarked and marks the negative one with the separate word no placed immediately before the verb, where nothing but an unstressed object pronoun may intervene, as in no lo vi. The verb carries no polarity suffix of its own, so the exponent is a free word rather than an inflection, which is the strategy the dimension permits alongside a bound one. A closed series of negative words, among them nada, nadie, nunca, ninguno and tampoco, pairs with the positive series algo, alguien, siempre, alguno and también, and in each pair the negative member is the marked one. When a negative word follows the verb, no is still required, and when it precedes the verb, no is dropped, as nunca lo vi and no lo vi nunca show; that alternation involves several interacting elements across the clause, which the dimension holds outside its scope, and this record does not treat it as a second value. Wherever a negative reading is intended the marking is required, which is what the obligatory value records.
