The Cambridge Handbook of Communication Disorders examines the full range of developmental and acquired communication disorders and provides the most up-to-date and comprehensive guide to the epidemiology, aetiology and clinical features of these disorders.
Elly van Gelderen provides examples of linguistic cycles from a number of
languages and language families, along with an account of the linguistic
cycle in terms of minimalist economy principles. A cycle involves
grammaticalization from lexical to functional category followed by renewal.
Some well-known cycles involve negatives, where full negative phrases are
reanalyzed as words and affixes and are then renewed by full phrases again.
Verbal agreement is another example: full pronouns are reanalyzed as
agreement markers and are renewed again. Each chapter provides data on a
separate cycle from a myriad of languages. Van Gelderen argues that the
cross-linguistic similarities can be seen as Economy Principles present in
the initial cognitive system or Universal Grammar. She further claims that
some of the cycles can be used to classify a language as analytic or
synthetic, and she provides insight into the shape of the earliest human
language and how it evolved.
