Advanced Learners Dictionary

Advanced Learners Dictionary - Dr Keith Brown

A dictionary, sometimes known as a wordbook, is a collection of words in one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologies, phonetics, pronunciations, translation, etc. or a book of words in one language with their equivalents in another, sometimes known as a lexicon. It is a lexicographical product which shows inter-relationships among the data.

A broad distinction is made between general and specialized dictionaries. Specialized dictionaries include words in specialist fields, rather than a complete range of words in the language. Lexical items that describe concepts in specific fields are usually called terms instead of words, although there is no consensus whether lexicology and terminology are two different fields of study. In theory, general dictionaries are supposed[citation needed] to be semasiological, mapping word to definition, while specialized dictionaries are supposed to be onomasiological, first identifying concepts and then establishing the terms used to designate them. In practice, the two approaches are used for both types. There are other types of dictionaries that do not fit neatly into the above distinction, for instance bilingual (translation) dictionaries, dictionaries of synonyms (thesauri), and rhyming dictionaries. The word dictionary (unqualified) is usually understood to refer to a general purpose monolingual dictionary.

The advanced learner's dictionary is the most common type of monolingual learner's dictionary, that is, a dictionary written for someone who is learning a foreign language and who has a proficiency level of B2 or above according to the Common European Framework. It differs from a bilingual or translation dictionary, on the one hand, and a standard dictionary written for native speakers or linguistic scholars, on the other. The definitions are usually built on defining vocabulary.

Although advanced learner's dictionaries have been produced for learners of several languages (including Chinese, Dutch, German, and Spanish) the majority are written for learners of English.
