In order to do so, conditional conjunctions were considered as they are listed by the grammars of Portuguese. The studied carried out here shows there is a wide group of conditional conjunctions, though the specialized literature focus on the conjunction se ‘if’ only. The analysis revealed that conditionality is realized by the expression of different conditional meanings, here called positive restrictive, negative restrictive and hypothetic. Moreover, taking into account that conditional markers have different meanings, conditional clauses were also analyzed in order to verify whether the different meanings can bring any influence over the clause construction. In order to do that, this paper analyzed conditionals clauses in the terms of the modifier typology put forward by Functional Discourse Grammar. As a result, we found out that the conditional meaning of the marker has no effect over the clause. Keywords Conditional conjunctions; positive restrictive; negative restrictive and hypothetic
