This book presents a comprehensive, state-of-the-art treatment of the acquisition of Indo- and Non-Indo-European languages in various contexts, such as L1, L2, L3/Ln, bi/multilingual, heritage languages, pathology as well as language impairment, and sign language acquisition. The book explores a broad mix of methodologies and issues in contemporary research. The text presents original research from several different perspectives, and provides a basis for dialogue between researchers working on diverse projects with the aim of furthering our understanding of how languages are acquired. The book proposes and refines new theoretical constructs, e.g. regarding the complexity of linguistic features as a relevant factor forming children's, adults' and bilingual individuals' acquisition of morphological, syntactic, discursive, pragmatic, lexical and phonological structures. It appeals to students, researchers, and professionals in the field.

This volume presents a collection of new articles that investigate the acquisition of Romance languages across different acquisition contexts as well as refine and propose new theoretical constructs such as complexity of linguistic features as a relevant factor forming children's, adults', and bilinguals' acquisition of syntactical, morphological, and phonological structures.

Traditional grammars have stated that clitics are subject or object pronouns whose distributional features make them different from personal pronouns. This book focuses on the acquisition of personal and demonstrative pronouns as well as clitics with respect to determinative phrases in a variety of languages of the Romance family and several indigenous languages, such as Quechua. A particularlyoriginal aspect of the present volume is that it not only addresses syntactic issues, but also semantic and pragmatic questions that have been widely neglected in the literature. It also reports on acquisition data of languages, such as Quechua, which have not attracted the attention of researchers until very recently.
