This chapter surveys language in the multilingual university at the levels of institutional policies, language practices in higher education and professional activities, and related beliefs about language use. The distinct political and historical contexts that shape language use in universities are taken into account by drawing on studies from various geo-linguistic contexts. Among the languages used, English plays a prominent role as the major language for research communication and increasingly as a viable language choice for teaching and learning in non-anglophone countries. Yet, language is not a neutral medium for accessing knowledge but entangled in questions of social justice.
