The `!advanced learner's dictionary`! is the most common type of `F33f`_`[monolingual learner's dictionary`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Monolingual_learner's_dictionary]`_`f, that is, a `F33f`_`[dictionary`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Dictionary]`_`f written in one language only, for someone who is learning a `F33f`_`[foreign language`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Foreign_language]`_`f. It differs from a `F33f`_`[bilingual`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Bilingual_dictionary]`_`f or `F33f`_`[translation`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Translation]`_`f dictionary, a standard dictionary written for `F33f`_`[native speakers`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Native_speakers]`_`f, or a children's dictionary. Its definitions are usually built on a restricted `F33f`_`[defining vocabulary`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Defining_vocabulary]`_`f. "Advanced" usually refers learners with a proficiency level of B2 or above according to the `F33f`_`[Common European Framework`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Common_European_Framework_of_Reference_for_Languages]`_`f. Basic learner's dictionaries also exist.
Although these advanced dictionaries have been produced for learners of several languages (including Chinese, Dutch, German, and Spanish), the majority are written for `F33f`_`[learners of English`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=English_as_a_second_or_foreign_language]`_`f.
