Research on left periphery phenomena has increased in the last 20 years, resulting in consistent studies from a wide range of languages and a fruitful debate on the functional projections within the CP system. Throughout these years, important contributions have been made on Brazilian Portuguese, especially on wh-interrogative sentences, focalization, topicalization and relative clauses. As for exclamative and imperative sentences, however, there is a considerable research gap in all grammatical levels. Regarding interrogatives, semantic and prosodic studies are still lacking (as well as research on the acquisition and processing of these constructions). This collected volume fills some of those gaps, gathering studies on wh-exclamatives, imperatives and wh-questions in Brazilian Portuguese which approach syntactical, semantical and prosodic aspects of these constructions through a rich and unregistered set of data. They also deliver novel acquisition and diachronic data that will further both the comprehension of Brazilian Portuguese grammar and the ongoing discussions on left periphery phenomena.

Current semantic fieldwork research has shown that the study of modality cannot be conducted via translation alone, yet much of what we know about modal expressions across the world's language is still translation-based. This book aims to facilitate the study of modality across more diverse languages and a wider participant base by explaining and illustrating a nuanced set of methods, including storyboards, questionnaires, corpora research, experimental tasks, as well as a discussion of practical semantic fieldwork techniques. The methodological protocols tested and employed by the authors on underdescribed languages - spanning seven different language families - are intended to be applicable as cross-linguistic tools, while also indicating the successes and challenges of their contributions. Expanding the study of modality to a wider set of underdescribed languages will undoubtedly bring new insights into our theoretical understanding of modality and deepen our understanding of a cross-linguistic typology of modal expressions.
