The purpose of this article is to investigate spaces of ambiguous transaction from the hermeneutical perspective of a diatopical poetic position. The article considers the Spanish language as spoken by the mapuche population as a space of ambiguous transaction because of its historically colonial and ambiguous condition. The article proposes the hermeneutical concept of a crack (rupture) to contrast and make visible the tensions contained within this space. This has a double purpose. On the one hand it intends to bring forth the alterity contained within it, and on the other hand it intends to better understand the naturalization behind the perception of this alterity. The overall purpose is to bind together a hermeneutical form which can illuminate both the “object” (as other) as well as the perception of the object (as self) in one and the same investigative movement.
