A defining vocabulary is a list of words used by lexicographers to write dictionary definitions. The underlying principle goes back to Samuel Johnson's notion that words should be defined using 'terms less abstruse than that which is to be explained', [1] and a defining vocabulary provides the lexicographer with a restricted list of high-frequency words which can be used for producing simple definitions of any word in the dictionary.
Defining vocabularies are especially common in English monolingual learner's dictionaries. The first such dictionary to use a defining vocabulary was the New Method English Dictionary by Michael West and James Endicott (published in 1935), a small dictionary written using a defining vocabulary of just 1,490 words. When the Longman Dictionary of Contemporary English was first published in 1978, its most striking feature was its use of a 2,000-word defining vocabulary based on Michael West's General Service List, and since then defining vocabularies have become a standard component of monolingual learner's dictionaries for English and for other languages.
Using a defining vocabulary is not without its problems, and some scholars have argued that it can lead to definitions which are insufficiently precise or accurate, or that words in the list are sometimes used in non-central meanings. [2] The more common view, however, is that the disadvantages are outweighed by the advantages, [3] [4] and there is some empirical research which supports this position. [5] Almost all English learner's dictionaries have a defining vocabulary, and these range in size between 2000 and 3000 words, for example:
It is possible that, in electronic dictionaries at least, the need for a controlled defining vocabulary will disappear. In some online dictionaries, such as the Macmillan English Dictionary for Advanced Learners , [6] every word in every definition is hyperlinked to its own entry, so that a user who is unsure of the meaning of a word in a definition can immediately see the definition for the word that is causing problems. However, this strategy works only if all the definitions are written in reasonably accessible language, which argues for some sort of defining vocabulary to be maintained in dictionaries aimed at language learners.
Intermediate-level language learners are likely to have receptive familiarity with most words in a typical 2,000-word defining vocabulary. To accommodate beginning-level learners, the defining vocabulary can be divided into two or more layers, where words in one layer are explained using only the simpler words from the previous layers. [7] This strategy is used in the Learn These Words First multi-layer dictionary, where a 360-word beginning-level defining vocabulary is used to explain a 2,000-word intermediate-level defining vocabulary, which in turn is used to define the remaining words in the dictionary.

A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically, which may include information on definitions, usage, etymologies, pronunciations, translation, etc. It is a lexicographical reference that shows inter-relationships among the data.
Lexicography is the study of lexicons, and is divided into two separate academic disciplines. It is the art of compiling dictionaries.
A thesaurus, sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings, sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms. They are often used by writers to help find the best word to express an idea:
...to find the word, or words, by which [an] idea may be most fitly and aptly expressed
A vocabulary is a set of familiar words within a person's language. A vocabulary, usually developed with age, serves as a useful and fundamental tool for communication and acquiring knowledge. Acquiring an extensive vocabulary is one of the largest challenges in learning a second language.
A monolingual learner's dictionary (MLD) is designed to meet the reference needs of people learning a foreign language. MLDs are based on the premise that language-learners should progress from a bilingual dictionary to a monolingual one as they become more proficient in their target language, but that general-purpose dictionaries (aimed at native speakers) are inappropriate for their needs. Dictionaries for learners include information on grammar, usage, common errors, collocation, and pragmatics, which is largely missing from standard dictionaries, because native speakers tend to know these aspects of language intuitively. And while the definitions in standard dictionaries are often written in difficult language, those in an MLD use a simple and accessible defining vocabulary.
In corpus linguistics, a collocation is a series of words or terms that co-occur more often than would be expected by chance. In phraseology, a collocation is a type of compositional phraseme, meaning that it can be understood from the words that make it up. This contrasts with an idiom, where the meaning of the whole cannot be inferred from its parts, and may be completely unrelated.
A language-for-specific-purposes dictionary is a reference work which defines the specialised vocabulary used by experts within a particular field, for example, architecture. The discipline that deals with these dictionaries is specialised lexicography. Medical dictionaries are well-known examples of the type.
An electronic dictionary is a dictionary whose data exists in digital form and can be accessed through a number of different media. Electronic dictionaries can be found in several forms, including software installed on tablet or desktop computers, mobile apps, web applications, and as a built-in function of E-readers. They may be free or require payment.
Japanese dictionaries have a history that began over 1300 years ago when Japanese Buddhist priests, who wanted to understand Chinese sutras, adapted Chinese character dictionaries. Present-day Japanese lexicographers are exploring computerized editing and electronic dictionaries. According to Nakao Keisuke (中尾啓介):
It has often been said that dictionary publishing in Japan is active and prosperous, that Japanese people are well provided for with reference tools, and that lexicography here, in practice as well as in research, has produced a number of valuable reference books together with voluminous academic studies.

A bilingual dictionary or translation dictionary is a specialized dictionary used to translate words or phrases from one language to another. Bilingual dictionaries can be unidirectional, meaning that they list the meanings of words of one language in another, or can be bidirectional, allowing translation to and from both languages. Bidirectional bilingual dictionaries usually consist of two sections, each listing words and phrases of one language alphabetically along with their translation. In addition to the translation, a bilingual dictionary usually indicates the part of speech, gender, verb type, declension model and other grammatical clues to help a non-native speaker use the word. Other features sometimes present in bilingual dictionaries are lists of phrases, usage and style guides, verb tables, maps and grammar references. In contrast to the bilingual dictionary, a monolingual dictionary defines words and phrases instead of translating them.
The advanced learner's dictionary is the most common type of monolingual learner's dictionary, that is, a dictionary written in one language only, for someone who is learning a foreign language. It differs from a bilingual or translation dictionary, a standard dictionary written for native speakers, or a children's dictionary. Its definitions are usually built on a restricted defining vocabulary. "Advanced" usually refers learners with a proficiency level of B2 or above according to the Common European Framework. Basic learner's dictionaries also exist.
The General Service List (GSL) is a list of roughly 2,000 words published by Michael West in 1953. The words were selected to represent the most frequent words of English and were taken from a corpus of written English. The target audience was English language learners and ESL teachers. To maximize the utility of the list, some frequent words that overlapped broadly in meaning with words already on the list were omitted. In the original publication the relative frequencies of various senses of the words were also included.
The Longman Dictionary of Contemporary English (LDOCE), first published by Longman in 1978, is an advanced learner's dictionary, providing definitions using a restricted vocabulary, helping non-native English speakers understand meanings easily. It is available in four configurations:

Macmillan English Dictionary for Advanced Learners, also known as MEDAL, was first published in 2002 by Macmillan Education. MEDAL is an advanced learner’s dictionary and shares most of the features of this type of dictionary: it provides definitions in simple language, using a controlled defining vocabulary; most words have example sentences to illustrate how they are typically used; and information is given about how words combine grammatically or in collocations. MEDAL also introduced a number of innovations. These include:
An explanatory combinatorial dictionary (ECD) is a type of monolingual dictionary designed to be part of a meaning-text linguistic model of a natural language. It is intended to be a complete record of the lexicon of a given language. As such, it identifies and describes, in separate entries, each of the language's lexemes and phrasemes. Among other things, each entry contains (1) a definition that incorporates a lexeme's semantic actants (2) complete information on lexical co-occurrence ; (3) an extensive set of examples. The ECD is a production dictionary — that is, it aims to provide all the information needed for a foreign learner or automaton to produce perfectly formed utterances of the language. Since the lexemes and phrasemes of a natural language number in the hundreds of thousands, a complete ECD, in paper form, would occupy the space of a large encyclopaedia. Such a work has yet to be achieved; while ECDs of Russian and French have been published, each describes less than one percent of the vocabulary of the respective languages.
Sketch Engine is a corpus manager and text analysis software developed by Lexical Computing CZ s.r.o. since 2003. Its purpose is to enable people studying language behaviour to search large text collections according to complex and linguistically motivated queries. Sketch Engine gained its name after one of the key features, word sketches: one-page, automatic, corpus-derived summaries of a word's grammatical and collocational behaviour. Currently, it supports and provides corpora in 90+ languages.
Tom McArthur was a Scottish linguist, lexicographer, and the founding editor of English Today. Among the many books he wrote and edited, he is best known for the Longman Lexicon of Contemporary English, the first thematic monolingual learner's dictionary, which complemented the Longman Dictionary of Contemporary English by bringing together sets of words with related meanings, Worlds of Reference, as well as the Oxford Guide to World English.
