These lectures examine the grammatical changes that took place in the transition from Latin to the Romance languages focusing on three fundamental areas: noun phrase, verb phrase, and sentence. While the specific details of the complex morphosyntactic changes are relatively well known, scholars are still divided as to their correct interpretation, and how they are to be integrated within the overall typological change(s) in the passage from Latin to Romance. I shall review a number of these competing approaches, comparing how individual developments (syntheticity vs analyticity; non-configurationality vs configurationality; (dis)harmonic linearization in terms head-final vs head-initial structures; head- vs dependent-marking; nominative-accusative vs active-stative alignments) can best be accounted for across different theories and approaches, emphasizing how a number of traditional ideas can be profitably reinterpreted in light of recent theoretical developments, highlighting what further insights, if any, they provide for our overall understanding of the nature of the broad typological and structural changes that differentiate the morphosyntax of the Romance languages from that of Latin
