Mexican Spanish in the Twentieth Century explores the trends and patterns of sociolinguistic stratification and variation, providing a clearer understanding of linguistic variation in Mexican Spanish as spoken in the twentieth century. The connection between past and present is evidenced through language data on Mexican Spanish gathered from various sources. The historical background of the nineteenth and twentieth centuries is revisited from the standpoint of stratification, conflict, and economic adjustments that fit within the model of modernity. This book advances both theoretical and methodological applications deemed necessary to crafting new research perspectives in Latin American sociolinguistics and the sociology of language. Seminal literary samples of Mexican and Latin American literature are presented systematically to exemplify the presence and vitality of linguistic variables along with their historical and social cultural context, offering a comprehensible and digestible approach to this field of study. Mexican Spanish in the Twentieth Century is a comprehensive volume for students and researchers of Hispanic linguistics, dialectology, and sociolinguistics. It will appeal to readers with an interest in the diversity of Latin American Spanish.
