This thesis examines the language policy and the role of English in Brussels, incorporating a small-scale study on language use and attitudes among people living in the city. The first part explores the theoretical background of language policy and planning (LPP), covering its emergence, evolution, and critical approaches. It also delves into LPP in Belgium, focusing on state reforms, linguistic freedom, and the principle of territoriality. Additionally, it discusses the concept of EuroEnglish and the unique linguistic context of Brussels, particularly regarding the increasing use of English due to globalization and immigration. The second part analyses the results of a questionnaire filled out by 55 Brussels residents. The questionnaire focused on the participants' language proficiency, attitudes towards English dominance, and frequency of English use in various domains. The study revealed that most participants acknowledged the practical benefits of English in Brussels but also expressed concerns about its potential to marginalize local language communities. Additionally, the frequency of English use was a predictor of support for the increased use of English in Brussels and the belief that making English an official language would not threaten local languages. Those who frequently used English expressed greater support for its expanded role in Brussels, viewing it as a valuable tool for communication and integration. Participants who used English more often were more inclined to support its increased use and official recognition, which underscores the pragmatic nature of language attitudes in a multilingual city like Brussels.
