This chapter provides an overview of the work on prosodic phonology and the syntax‐phonology interface in Brazilian Portuguese (BP) and European Portuguese (EP). It first reviews some of the phonological evidence for prosodic constituents in Portuguese, both of which articulated within the framework of prosodic phonology developed in Nespor and Vogel. As phonologists disagree on whether the lowest prosodic domain that interacts with syntax is the clitic group or the prosodic word, the chapter looks at the available evidence for the prosodic word level in both varieties of Portuguese and discusses the prosodic status of clitics and the internal prosodic structure of compounds. It then considers the phonological properties of higher levels of the prosodic hierarchy, namely, the phonological phrase and the intonational phrase. Next, the chapter surveys the construction of prosodic domains and the interaction between phonology and other components of the grammar.
