  1. Dictionary

    A dictionary is a collection of words in one or more specific languages, often listed alphabetically, with usage information, definitions, etymologies, phonetics, pronunciations, and other information; or a book of words in one language with their equivalents in another, also known as a lexicon. According to Nielsen a dictionary may be regarded as a lexicographical product that is characterised by three significant features: it has been prepared for one or more functions; it contains data that have been selected for the purpose of fulfilling those functions; and its lexicographic structures link and establish relationships between the data so that they can meet the needs of users and fulfill the functions of the dictionary. A broad distinction is made between general and specialized dictionaries. Specialized dictionaries do not contain information about words that are used in language for general purposes—words used by ordinary people in everyday situations. 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 don't fit neatly in the above distinction, for instance bilingual dictionaries, dictionaries of synonyms, or rhyming dictionaries. The word dictionary is usually understood to refer to a monolingual general-purpose dictionary.

Examples of dictionary in a Sentence

  1. Cheryl McDonald:

    They were yelling. I think the only words they know in the dictionary are profanity.

  2. Roberto Mukaro Borrero:

    The tweet by the Washington Redskins rings hollow to me. If the team was really interested in standing in solidarity for racial justice, they would change their name from the dictionary-defined racial slur they continue to use. As an indigenous person, I feel their tweet comes off as tone-deaf, not woke. Violence comes in many forms, some more subtle than others. Indigenous Peoples are not your mascots.

    The girl quoting the definitions before (pronouncer Jacques) Bailly said them stated the usage note from our unabridged dictionary verbatim. ... Its a very specific kind of writing that we do. I thought, Oh my goodness, this 13-year-old girl is quoting our dictionary back to us, these spellers as a group simply were unusually gifted. They may indicate that we have entered a new era of competition.
