The Syntactic Doubling of Relative-interrogative and Indefinite (Temporal, Modal and Quantitative Adverbials) through Corresponding Alterity Adverbials in Present-day Romanian. This study represents a continuation of a previous study (Chircu 2020b); it discusses the distribution of (temporal, modal and quantitative) alterity adverbials which syntactically double semantically equivalent relative-interrogative and indefinite adverbials. The alterity adverbials strengthen the meaning of the relative-interrogative and indefinite adverbials and offer alternative solutions of fulfilling the action expressed by the verb or, in the case of modal adverbials, of satisfying the constraints of a ternary relation. In the identified contexts, it can be observed that the alterity adverbial is used both anaphorically and cataphorically, depending of the choice of the speakers. For this analysis, the author has extracted data from the present-day language (the CoRoLa corpus and Google).
