This category is for articles related to specific bidirectional and bilingual dictionaries for various languages. These dictionaries can include any two-language pair; please create a subcategory for each such dictionary language if it does not already exist. For example, a Russian-Esperanto, Esperanto-Russian dictionary would be listed in two subcategories: Category:Esperanto bilingual dictionaries and Category:Russian bilingual dictionaries.
- Monolingual dictionaries should be listed in a subcategory of Category:Dictionaries by language. For example, a dictionary with French headwords accompanied by definitions in French should be categorized as Category:French dictionaries.
- Two-language dictionaries which translate in only one direction should be listed in a subcategory of Category:Translation dictionaries. For example, a dictionary with Welsh headwords accompanied by definitions in Ukrainian should be categorized as Category:Welsh translation dictionaries.
