This article explores the difference between equality and the absence of discrimination within the area of language use. It draws on examples of social practices of linguistic inequality in Slovakia, and analyses how these are regulated by Slovak law, international law and laws of countries of best practices. The article argues that these examples represent three different models of linguistic equality: formal equality, equality of opportunities and substantive linguistic equality. It will analyse how these approaches empower or disadvantage speakers of minority languages, and what normative guide they provide for linguistic equality.
