Spoken by millions of people on four continents, Portuguese remains a lesser studied language. To help improve the linguistic understanding of this pluricentric language, the present volume brings together twelve studies about different grammatical phenomena observed in Portuguese varieties – from suffixation to intercalated temporal clauses and non-concatenative verbal inflection, among other topics. Focusing on three main axes – usage, cognition and teaching –, these studies draw on the theoretical frameworks of Functional Linguistics and Cognitive Linguistics, but build a cohesive whole insofar as they all offer usage-based language approaches. By presenting an overview of recent research on Portuguese and its varieties, the book paves the way for the inclusion of Portuguese in the set of Neo-Latin languages best known to the general public.
