Nonpassive Verbal Periphrases in the Romance Languages
Verbal periphrases combine two verbal forms that share their arguments. One of the forms, [V2], lexically determines most of the argument structure of the whole construction, whereas the other, [V1], contributes the sort of abstract meaning usually associated with functional categories in the realms of tense, aspect, and modality and is often classified as a (semi-)auxiliary. In most cases, [V2] appears in a fixed nonfinite form (infinitive, gerund, or participle), whereas the inflection on [V1] is variable; the periphrastic pattern may also include a preposition introducing the nonfinite form. Research on verbal periphrases has concentrated on the differences between periphrastic patterns and free patterns of complementation or adjunction involving nonfinite clauses, on the syntactic analysis of those patterns, and on their semantic classification. The renewed interest in the field in recent years has two sources. On the one hand, research on grammaticalization has emphasized the importance of periphrases for our understanding of the way in which exponents for grammatical meanings emerge diachronically from lexical constructions. On the other hand, work in generative syntax (in the so-called cartographic approach) has taken periphrases as evidence for the postulated existence of highly articulated functional layers above a core verb phrase headed by a lexical verb. The bulk of nonpassive verbal periphrases either modify Aktionsart or express viewpoint aspect or relative tense. Research has revealed considerable differences in their inventory and in the status of cognate periphrases across Romance, as well as some parallel or convergent developments.
