Dictionaries can be classified into different types depending on the number of languages they contain or the type of information they provide.
Dictionaries are categorized by the number of languages they contain. Monolingual dictionaries focus on one language, whereas bilingual and multilingual dictionaries include multiple languages. 'Quadratic dictionaries' is a non-standard term that might refer to dictionaries with four language components or definitions.
