Abstract
Structure mapping tackles the issue of syntactic complexity by attempting to draw maps as detailed as possible of the internal structure of phrases and sentences across languages and dialects (Rizzi & Cinque 2016). But how can we map an infinite space ? It's a matter of identifying stable syntactic configurations, which recursively embed into one another. In this lecture, we will trace the development of the cartographic study of the sentence and its initial periphery, the complement system. In the quest for these stable structures, we need to consider two interfaces internal to the linguistic computation system, the interface with the lexicon on the one hand and morphology on the other : through these two " doors " syntax exchanges information with the lexical representations and morphological structures of the language.
