This article on the general operation of otherness which gathers five discursive particles is aimed to underscore the signification of each one of them. The first one, àshée, presupposes an earlier valid utterance then it introduces ist opposite as now valid. With gîdèe, the two utterances are produced by different subjects, the one under the scope of gîdèe being already valid, what the other subject ignored. As for ányáa, considered a previously constructed assertion, it modifies the content of the assertion by introducing a value of doubt. The two last particles also bring together two different occurences with many variations richer for àmmáa than for áy, which needs in addition the same utterer for the two utterances in opposition.
