El castellà, la llengua del costat

In Catalonia, now, millions of Catalans speak Spanish. But we very surprising that a Catalan speaker does not know Spanish. We forgot that Spanish was "the language of the side". In fact, at times we seem to have forgotten that they are two different languages. How was Spanish introduced in Catalonia? How did our great-grandmothers learn it when there were no Tele5, COPE, or Netflix series? This book approaches in a fun and entertaining way the role of 15th-century Spanish at the gates of the 20th, with the definitive universal schooling in Spanish. The extension of Spanish to Catalonia has a complex story that can be told with rigor and humor. What experiences did the Catalans have with "the tongue of the side"?
