Book excerpt: This third volume of the Interfaces in Language series brings together a collection of papers which were presented at the University of Kent’s Interfaces in Language 3 conference of May 2011. In line with the conference’s title, applications which held true to the interface theme were invited, yet no restrictions were placed on the way in which ‘interface’ was interpreted. A range of talks were thus included, some of which conformed to established demarcations within the discipline, others of which flouted them entirely and unashamedly. All were welcome. The result was a heterogeneous set of talks, interspersed with and complemented by lively discussions, confirming that the interdisciplinary setting staged was a successful way of cultivating discussion between linguists who might otherwise not cross paths. The papers chosen for publication here include both diachronic and synchronic approaches to language, generative and non-generative frameworks, as well as typological and theory-driven perspectives. The result can only be described as an eclectic mix. We invite the reader to decide upon its success.
