'This excellent third volume of Roberts' syntax trilogy introduces students to generative theories of linguistic typology: why does the grammar of languages vary in just the way it does? The book expertly explains fundamental concepts, generalisations, and phenomena. Novel problem sets, end-of-chapter reading lists, and a glossary make it uniquely helpful to intermediate and advanced syntax students.' David Adger, Queen Mary University London
