A dictionary contains a list of words, usually in alphabetical order, along with the definition or meaning of each word. Examples of usage, pronunciations, and translations may also be included.
A thesaurus, sometimes referred to as a synonym dictionary, is a reference book or electronic resource used to find synonyms, and sometimes antonyms, of words.
Special dictionaries are used for more specific purposes. For example, bilingual dictionaries are used to translate words from one language to another, and medical and legal dictionaries may be used to assist with learning terminology related to those specific fields.
