evidentiality in Rioplatense Spanish

Rioplatense Spanish has no evidential paradigm. No suffix, pronoun or particle marks a proposition as seen, inferred, reported or assumed, and a speaker who needs the source of information stated does so in words, with a verb such as vi, escuché or me dijeron, or with an adverbial such as por lo visto or según. One candidate might have qualified and does not. The inflected future and the conditional carry an inferential reading, so serán las tres is understood as an estimate about the present rather than as a claim about the future, and habría salido can report an inference rather than an unrealised past. That reading is a secondary use of a tense form rather than a form dedicated to the meaning, it is never required in any context, and it draws no contrast across a closed set of information sources, which is what a system of this kind consists in. The absence recorded here is an assertion about the language and not a gap in the description of it.
