All languages encode aspects of culture and every culture has its own specificities to be proud of and to be transmitted. The papers in this book explore aspects of this relationship between language and culture, considering issues related to the processes of internationalization and localization of the English language. The volume is divided into two sections, complementing each other; the first one (Localizing English) focuses on the significance of ethnic knowledge, local culture, and tradition wherever English is used. The second one (Internationalizing English) deals with the degrees and patterns of internationalization of English deriving from its contact with diverse cultures and its adaptation to different professional settings and communicative purposes.
