The most popular dictionary and thesaurus for learners of English. Meanings and definitions of words with pronunciations.
In many languages, such as the English language, the pronunciation of some words is not consistently apparent from their spelling. In these languages, dictionaries usually provide the pronunciation. For example, the definition for the word dictionary might be followed by the International Phonetic Alphabet spelling /ˈdɪkʃənəri/ (in British English) or /ˈdɪkʃənɛri/ (in American English). American English dictionaries often use their own pronunciation respelling systems with diacritics, for example dictionary is respelled as "dĭk′shə-nĕr′ē" in the American Heritage Dictionary.[30] The IPA is more commonly used within the British Commonwealth countries. Yet others use their own pronunciation respelling systems without diacritics: for example, dictionary may be respelled as DIK-shə-nerr-ee. Some online or electronic dictionaries provide audio recordings of words being spoken.
The simplest dictionary, a defining dictionary, provides a core glossary of the simplest meanings of the simplest concepts. From these, other concepts can be explained and defined, in particular for those who are first learning a language. In English, the commercial defining dictionaries typically include only one or two meanings of under 2000 words. With these, the rest of English, and even the 4000 most common English idioms and metaphors, can be defined.
A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologies, pronunciations, translation, etc.. It is a lexicographical reference that 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 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.
There is also a contrast between prescriptive or descriptive dictionaries; the former reflect what is seen as correct use of the language while the latter reflect recorded actual use. Stylistic indications (e.g. "informal" or "vulgar") in many modern dictionaries are also considered by some to be less than objectively descriptive.
Although the first recorded dictionaries date back to Sumerian times (these were bilingual dictionaries), the systematic study of dictionaries as objects of scientific interest themselves is a 20th-century enterprise, called lexicography, and largely initiated by Ladislav Zgusta. The birth of the new discipline was not without controversy, the practical dictionary-makers being sometimes accused by others of "astonishing" lack of method and critical-self reflection.
In a general dictionary, each word may have multiple meanings. Some dictionaries include each separate meaning in the order of most common usage while others list definitions in historical order, with the oldest usage first.
