Um percurso teórico-metodológico para o estudo de constela？？es de gêneros

in this essay, i propose a theoretical-methodological journey that permits to substantiate a possible reflection about the phenomenon of discursive genre grouping. therefore, i undertake an analysis of the arguments of marcuschi (2000) and bakhtin ([1929] 2002) about the groups of genres. although there are discrepancies between both proposals for conceiving a constellation of genres, it is possible to establish a consensual point between these researchers in that both highlight the tendencies of the genres to variations and transmutations. the effects of this analysis permit the conclusion that a study which will undertake the characterization of a genre constellation must be structured from three fundamental thematic axles: the sphere(s) of communication in which such genres adapt themselves; the tracks left during its process of formation and the communicative purposes attended by each genre inside the constellation.
