monolingual

This term describes a state of linguistic singularity, often carrying a neutral descriptive tone in academic contexts but shifting toward a negative connotation in discussions about globalization or cognitive flexibility. It suggests a limitation of scope, contrasting sharply with bilingualism or multilingualism.

When used to describe a dictionary, the term specifies a tool for immersion, where the user is forced to engage with the target language without the safety net of a native tongue. This distinguishes it from bilingual dictionaries, which rely on translation between two different languages.
