Book excerpt: In this collection of carefully selected papers connectivity is looked at from the vantage points of language contact, language change, language acquisition, multilingual communication and related domains based on various European and Non-European languages. From typological and multilingual perspectives the focus of investigation is on the grammatical architecture of a number of linguistic devices that interconnect units of text and discourse. The volume is organized along central concepts: A general section deals with connectivity in language change and language acquisition, subdivisions are devoted to pronouns, topics and subjects, the role of finiteness in text and discourse, coordination and subordination and particles, adverbials and constructions. The editors' preface introduces connectivity as an object of linguistic research.
