Linguistic Cycles are ever present in language change and involve a phrase or word that gradually disappears and is replaced by a new linguistic item. The most well-known cycles involve negatives, where an initial single negative, such as 'not,' is reinforced by another negative, such as 'no thing', and subjects, where full pronouns are reanalyzed as endings on the verb. This book presents new data and insights on the well-known cyclical changes as well as on less well-known ones, such as the preposition, auxiliary, copula, modal, and complementation cycles. Part I covers the negative cycle with chapters looking in great detail at the steps that are typical in this cycle. Part II focuses on pronouns, auxiliaries, and the left periphery. Part III includes work on modals, prepositions, and complementation. The book ends with a psycholinguistic chapter. This book brings together linguists from a variety of theoretical frameworks and contributes to new directions in work on language change.
