Is historical linguistics different in principle from other linguistic research? This book addresses problems encountered in gathering and analysing data from early English, including the incomplete nature of the evidence and the dangers of misinterpretation or over-interpretation. Even so, gaps in the data can sometimes be filled. The volume brings together a team of leading English historical linguists who have encountered such issues first-hand, to discuss and suggest solutions to a range of problems in the phonology, syntax, dialectology and onomastics of older English. The topics extend widely over the history of English, chronologically and linguistically, and include Anglo-Saxon naming practices, the phonology of the alliterative line, computational measurement of dialect similarity, dialect levelling and enregisterment in late Modern English, stress-timing in English phonology and the syntax of Old and early Modern English. The book will be of particular interest to researchers and students in English historical linguistics.
