The book provides a new insight into English-Polish comparative sociolinguistics by comparing and contrasting the attitudes of young adult native speakers of British English and Polish towards the standard varieties of their mother tongues. The author reviews the Anglophone and Polish approaches to standard dialects and language standardization, integrating sociolinguistics, normative linguistics and prescriptivism. The core of the work presents and analyses the results of a questionnaire-based study of language attitudes conducted at several Polish and British universities. In conclusion, the author places the two groups of informants on a spectrum of language attitudes ranging from purism to tolerance of non-standard varieties.
