A interacção dos tempos verbais e dos adverbiais circunstanciais na construção de um valor aspectual

In this paper we will analyze semantic relations between various types of adverbials and grammatical tenses. As we shall see, it is necessary that adverbials which occur in statements do not come into contradiction with essential values represented by morphemes of verbal flexion. On the contrary, adverbials can block the use of certain grammatical tenses. In particular, we will discuss all cases of interpropositional incompatibility between the referred constituents of a statement, always motiwated [i.e. motivated] by semantic reasons.
