Dictionary may refer to any of the following:

Thesaurus and Dictionary

1. A dictionary is an alphabetical listing of words and their meanings. Dictionaries help users look up definitions to get a better understanding of the word and an overall better understanding of a language or field. Many computers do not include an electronic dictionary, however, with access to the Internet, there are hundreds of free online dictionaries.

Dictionary v.s. thesaurus

A dictionary describes the meaning of a word. A thesaurus is used to group different words with the same meaning (synonyms) and similar words. For example, looking up the word "computer" in a dictionary would define the word like what is found on our computer definition. Looking up the word "computer" in a thesaurus may give words like PC, CPU, calculator, abacus, and laptop that could be used in place of the word computer.

Why would someone need a dictionary on a computer?

On a computer, a dictionary is most often used to check the user's spelling, and sometimes to find word meanings, synonyms, and antonyms.

2. Dictionary is a term sometimes used to describe an associative array.
