The claim that “…pronominals have phonological features only where they must, for some reason”, is strongly supported by the occurrence of the null pronoun PRO as coined and introduced by Noam Chomsky. How reference of PRO is determined is the main subject of control theory, the subsystem of core grammar to which this study is dedicated. Chomsky has not followed up his “natural suggestion that choice of controller is determined by theta roles or other semantic properties of the verb, perhaps pragmatic conditions of some sort.”

The papers collected in this volume were first presented at the 14th International Conference on English Historical Linguistics (Bergamo, 2006). Alongside studies of syntax, morphology, and dialectology, published in two sister volumes, many innovative contributions focused on semantics, pragmatics and register variation. A rich variety of state-of-the-art studies and plenary lectures by acknowledged world experts in the field bears witness to the quality of the scholarly interest in this field of research.

Second language acquisition has to integrate the totality of the SLA process, which includes both the learning of the core syntax of a language and the learning of the lexical items that have to be incorporated into that syntax. But these two domains involve different kinds of learning. Syntax is learnt through a process of implementing a particular set of universal structures, whereas the learning of lexis is characterised by the building up of associations (or connections). Yet these two systems must come together in the creation of a whole linguistic system in the mind of an individual.

Understanding sociolinguistics as a theoretical and methodological framework hopefully could attempt to promote change and social development in human communities. Yet it still presents important political, epistemological, methodological and theoretical challenges. A sociolinguistics of development, in which the revitalization of linguistic communities is the priority, opens new perspectives for the emerging field of linguistic documentation, in which the societal aspects of research, stressed by sociolinguistics, have frequently been marginal.

This book considers linguistic and mental representations of time. Prominent linguists and philosophers from all over the world examine and report on recent work on the representation of temporal reference; the interaction of the temporal information from tense, aspect, modality, temporal adverbials, and context; and the representation of the temporal relations between events and states, as well as between facts, propositions, sentences, and utterances. They link this to current research on the cognitive processing of temporal reference, linguistic and philosophical semantics, psychology, and anthropology.
