information structure in Rioplatense Spanish

Rioplatense Spanish has no affix or particle for either of the two values this dimension admits. It packages a proposition by rearranging it. What the utterance is about is commonly placed before the clause and picked up inside it by an unstressed pronoun, as in a Juan lo vi ayer, where the object is announced first and lo carries it back into its ordinary position. The asserted part can be fronted without that pronoun, as in eso quería, or isolated in a frame built on ser, as in fue Juan quien llegó. Prominence in the voice marks the asserted part in speech and leaves no trace in writing, which is the prosodic strategy the dimension names as widely available. The realizers are therefore multi element frames and an intonational process rather than forms, which is what the periphrastic state records, and the value is optional because a clause in neutral order is always available and commits the speaker to nothing about the packaging.
