Frases imperativas e negação em Português Europeu

Abstract

In languages like Spanish, Italian and European Portuguese, specific morphological verb forms alternate with suppletive verb forms to express imperative. However, they pattern differently with respect to sentential negation: true imperatives ban the occurrence of sentential negation in opposition to suppletive imperatives. This contrast has been ascribed to different causes: differences in the structural configuration of true and suppletive imperatives, distinct selectional properties of the functional projections involved, or scope constraints on the sentence illocutionary force. Focussing European Portuguese, we will set up the structure of imperative sentences, taking into account the evidence provided by sentence negation, the scope of the illocutionary force, the status of Tº and the position of overt subjects
