The paper proposes a novel way to unify Rough Set Theory and Formal Concept Analysis, drawing from results and insights in the algebraic theory of modal logic. It is based on the idea that Pawlak's original approximation spaces can be seen as special instances of enriched formal contexts, i.e. relational structures based on formal contexts from Formal Concept Analysis.
