Operadores de afirmación confirmativos. El caso de sipi en Twitter

This paper examines the behaviour of the affirmative operator sipi in a corpus composed of messages extracted from the social network Twitter. Through the analysisof its syntactic peculiarities and its particular pragmatic-discursive values -with the tools of metaoperational grammar- an attempt is made, on the one hand, to deny its consideration as a mere colloquial variant of the adverb of polarity itself and, on the other, to position it within a general mechanism of "unfolding" or “splitting” of affirmation and negation basic operators that in different languages gives rise to elements of discursive closure and confirmatory value.
