Middle English [PDF ebook] 

This volume provides a wide-ranging account of Middle English, organized by linguistic level. Not only are the traditional areas of linguistic study explored in state-of-the-art chapters on Middle English phonology morphology, syntax, and semantics written by experts in the field, but the volume also covers less traditional areas of study, including Middle English creolization, sociolinguistics, literary language (including the language of Chaucer), pragmatics and discourse, dialectology, standardization, language contact, and multilingualism.
