I understand the differentiation between primary and secondary genres contains elements not completely clear concerning Bakhtine's conception of discourse genres. Therefore, after presenting the reflection of some authors about such a distinction, I have proposed an enlargement of the few suggestions present in the Russian philosopher's theory, taking into consideration the conceptions of Russian psychologists Luria (1986), Vigotski (2001) and Elkonin (1998). I have also brought some enlightenment from the Theory of Enunciation (CULIOLI, 1997; VOGÜÉ, 1989). Such different approaches point to phenomena of plasticity and hybridity in the constitution of genres.
