Middle voice represents an inflexional category of classical Indo-European languages with the function of expressing states of affairs which affect the subject of the verb or its interests. In Portuguese there is a set of predicates, formally identified by an anaphorical but non-coreferential use of the pronoun 'se', which supports the notion of middle diathesis. This paper aims at providing formal, semantic and typological evidences in order to postulate a distinction between middle and reflexive-reciprocal constructions.
