The acquisition of the definite article by LS/L2 Italian learners represents a very delicate issue, on the one hand, in relation to the mother tongue and other known languages and, on the other, to the range of uses of this part of the discussion (among others, cf. Chini 1995a; Pallotti 1998). The research is exploratory, and the results allow us to examine a sector of applied linguistics and language teaching that is still little investigated (Krámský 2016).
