Pragma-dialectical approach, due to its research agenda, has entered into fruitful dialogue with the theoretical perspective offered by theorists of Lugano School. In Spanish language there’s been a poor reference, or no reference at all, of this dialogue. This paper wants to provide a first approach to the way the scholars of Lugano understand argumentation and to some instruments proposed by them for analysis and evaluation of arguments. It is expected, on the one hand, to spread the work of these scholars in hispanic-american ambit, and on the other hand to contribute to the discussion about pragma-dialectics in the theory of argumentation.
