This book investigates the syntactic organization of the higher functional field within the clause by analyzing micro-variations across Northern Italian dialects. Cecilia Poletto, a specialist in comparative syntax, utilizes a vast corpus of dialectal data to map the structural hierarchy of the left periphery. The work argues that these dialects provide a unique laboratory for observing syntactic parameters that remain obscured in more standardized languages, ultimately proposing a refined model for functional phrase structure.

Experts in the field of generative syntax recognize this work as a foundational text for understanding the left periphery of the clause. Readers frequently note the technical density of the prose, which is intended for advanced students and researchers of comparative linguistics.
