This volume in the Routledge Language Family Descriptions series describes, in depth, Celtic languages from historical, structural, & sociolinguistic perspectives with individual chapters on Irish, Scottish Gaelic, Manx, Welsh, Breton, & Cornish. The book consists of four parts. Part 1 discusses the origin & history of Celtic languages, their spread & retreat, present-day distribution, & typological profiles of the extant & recently extant languages. Parts 2 & 3 devote whole chapters to the description of the structural properties of each of the neo-Celtic languages, including their phonology, mutation, morphology, syntax, lexicon, & dialectology. Part 4 addresses sociolinguistic details identifying areal distribution, maintenance, & survival prospects. Z. Dubiel
