Dictionary

A dictionary is a list of words with their definitions, a list of characters with their glyphs, or a list of words with corresponding words in other languages. In some languages, words can appear in many different forms, but only the lemma form appears as the main word or headword in most dictionaries. Many dictionaries also provide pronunciation information; grammatical information; word derivations, histories, or etymologies; illustrations; usage guidance; and examples in phrases or sentences. Dictionaries are most commonly found in the form of a book.

Special-purpose dictionaries

There are many different types of dictionaries, including bilingual, multilingual, historical, biographical, and geographical dictionaries.

Bilingual dictionaries

In bilingual dictionaries, each entry has translations of words in another language. For example, in a Japanese-English dictionary, the entry tsuki has the corresponding English word, moon. In dictionaries between English and a language using a non-Roman script, entry words in the non-English language may either be printed and sorted in the native order, or romanized and sorted in Roman alphabetical order.

Specialized dictionaries

Specialized dictionaries (also referred to as technical dictionaries) focus on linguistic and factual matters relating to specific subject fields. A specialized dictionary may have a relatively broad coverage, in that it covers several subject fields such as science and technology (a multi-field dictionary), or their coverage may be more narrow, in that they cover one particular subject field such as law (a single-field dictionary) or even a specific sub-field such as contract law (a sub-field dictionary). Specialized dictionaries may be maximizing dictionaries, i.e. they attempt to achieve comprehensive coverage of the terms in the subject field concerned, or they may be minimizing dictionaries, i.e. they attempt to cover only a limited number of the specialized vocabulary concerned. Generally, multi-field dictionaries tend to be minimizing, whereas single-field and sub-field dictionaries tend to be maximizing. See also LSP dictionary.

Character dictionaries

In East Asian languages, a dictionary specialized in Han (Chinese) characters has developed, called Kan-wa jiten (literally 'Han-Japanese dictionary') in Japanese and Okpyeon ('Jewel Book') in Korean. Each entry has one Chinese character with information about stroke count and order, readings (pronunciations), and a list of words using that character.

Glossaries

Another variant is the glossary, an alphabetical list of defined terms in a specialized field, such as medicine or science. 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.
