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.

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.
