Monoglottism (Greek μόνοσ "monos", "alone, solitary", + γλώττα "glotta", "tongue, language") or, more commonly, monolingualism or unilingualism, is the condition of being able to speak only a single language, as opposed to multilingualism. In a different context, "unilingualism" may refer to a language policy which enforces an official or national language over others.
