This book offers an updated introduction to Relational Network Theory
(RNT), a neurocognitive model of language compatible with
systemic-functional tenets. It describes and illustrates the logical
types of relations found in a linguistic network. Part I traces the
evolution of RNT from the 1960s to the present, highlighting its
systemic and stratificational origins, introducing its main notational
devices, and identifying successive theoretical milestones (from
structural, to operational, to neurocognitive considerations). Part II
offers an unprecedented collection of case studies showing descriptive
applications of RNT. The studies deal with varied linguistic phenomena
in different languages (phonological patterns in Russian, morphological
systems in Polish and Spanish, pronouns and nouns in English discourse,
speech errors in English and Polish). The book is prefaced by Michael
Halliday and includes a recent interview with Sydney Lamb, the main
developer of the theory. Its didactic style and descriptive rigor render
it useful for both linguistics students and professional linguists.
