In this study we aim at examining the behaviour of the preposition “la” (“at/to”) in the Romanian language. The starting point of our analysis is represented by the distinctions made by the modern grammar between lexical/semi-lexical/functional prepositions. “La” (“at/to”) has, in Romanian, homonym forms which illustrate all these subcategories. We will highlight the differences in grammatical functionality between the used contexts; our study is discussing the capacity of this preposition to become a group centre, the assigning of a thematic role, the grammatical restrictions imposed on the dominated term.
This paper aims at analyzing the role of the preposition when it is used together with non-finite forms of the verb. We will examine the following aspects: the mixed features of the infinitive (substantival and verbal), the types of prepositions which can be combined with the non-finite forms of the verb (lexical, semi-lexical and functional), the ability of the preposition to generate a prepositional syntactic group, the setting/non-setting of a thematic role, the syntactic positions held by the infinitive with preposition. If the rule says that the preposition has a case government, we ask ourselves what happens to it in the presence of non-finite forms of the verb. Therefore, one of the discussed topics is the obstruction of the case government/practising it under the substantival features of the non-finite forms.
