A dictionary is a collection of words and their definitions, often arranged alphabetically. It is a reference tool used to look up the meanings of words, their spelling, pronunciation, etymology, and usage. Dictionaries are often used in learning a language and in writing to ensure that words are spelled correctly and used in the proper context. Dictionaries vary in size from small pocket-sized versions to large multivolume works made up of thousands of entries. They can be printed on paper or stored electronically on computers or other devices. The entries may include definitions, synonyms and antonyms, etymologies (the origin of a word), illustrative quotes from literature or other sources, pronunciations, sample phrases or sentences using the word, and cross-references for related words. Dictionaries typically contain both descriptive and prescriptive information about language usage; that is, they provide both descriptions of how words are actually used in contemporary language as well as advice on what forms should be preferred when speaking or writing. This prescriptive element can be helpful to learners who need guidance on how best to express themselves in a target language. The earliest dictionaries were monolingual—they provided definitions only for one language—but bilingual dictionaries began appearing during the 16th century. Today’s dictionaries may include multiple languages as well as technical terms from specialized fields such as medicine or law. In addition to being useful reference tools for writers and speakers of all kinds, dictionaries can also provide entertaining reading material for those interested in exploring the history of words and their various meanings over time.
