This book presents a new theory of grammatical categories - the Universal Spine Hypothesis - and reinforces generative notions of Universal Grammar while accommodating insights from linguistic typology.
The theory of communication series is suggested as an alternative to discourse linguistics because it focuses not only on mass communications with reference to a thematic context, but examines every social communication including interpersonal communication between two persons or within a small group. Each element of communication is subject to three areas of level: (1) speech act and speech act sequences; (2) communication (conversations, text-based communication); (3) series as purpose-constituted consequences of communication. Series can be recursively embedded, extending as far as society-related and international series. Series are diachronic quantities with evolutionary levels.
