Linguistic complexity: interfaces and processing

2017, Language Sciences

Abstract

Recently, various views have been proposed in the literature which challenge this consensus, thus suggesting that languages can differ fundamentally in complexity and that the degree of complexity of a language may correlate with the context in which it emerged (e.g., L1 acquisition versus L2 acquisition), its age (e.g., pidgins/creoles versus older languages), or the size and social structure of its speaking community (small tightly related communities versus large and loose communities), see e.g., Bickerton (1981, 1984, 1988), Dahl (2004), Trudgill (2011), among many others. In such views, languages acquire more complex systems as they evolve, hence notions such as growth or maturation (or grammaticalization) as argued for in Dahl (2004: 2). In this book, I look at grammaticalization in the perspective of what I call maturitydmature linguistic phenomena being those that presuppose a non-trivial prehistory: that is, they can only exist in a language which has passed through specific earlier stages. Grammatical maturationdprocesses that give rise to phenomena that are mature in this sensedin general adds to the complexity of a language [.] Complexity is here seen, not as synonymous with "difficulty" but as an objective property of a systemda measure of the amount of information needed to describe or reconstruct it. Applied to the following examples from English and Gungbe, we may reach the conclusion that the morphosyntax of the English past verb is more complex than that of the Gungbe one. In English, one needs to specify that regular verbs must take an additional affix to encode past, while no such affix is required in Gungbe: the verb is always bare in this language and past is the default interpretation for eventive (or so-called dynamic) verbs (cf. Aboh, 2004a). While this characterization of complexity may sometimes suggest that more superficial distinctions in a language may increase complexity, this need not be the case since what matters here is the amount of information required to describe or reconstruct the system (cf. Dahl, 2004, Audring, this volume).
