First published in 1986. For most of the authors represented in this collection, the term ''Sublanguage'' suggests a subsystem of language that behaves essentially like the whole language, while being limited in reference to a specific subject domain. Argued throughout this title, even if sublanguage grammars can be related to the grammar of the full standard language, sublanguages behave in many ways like autonomous systems. This volume will illustrate that, as such, they take on theoretical interest as microcosms of the whole language. The papers collected in this volume were presented at the Workshop on Sublanguage, held at New York University on January 19-20, 1984.
