Dictionary.com is an online dictionary whose domain was first registered on May 14, 1995.[1] The content for Dictionary.com is based on the latest version of Random House Unabridged Dictionary, with editors for the site providing new and updated definitions.[2][3] Supplementary content comes from the Collins English Dictionary, American Heritage Dictionary and others.[4]


Dictionary.com was founded by Brian Kariger and Daniel Fierro as part of Lexico Publishing, which also started Thesaurus.com and Reference.com.[5] At the time of its launch, it was one of the web's first in-depth reference sites.[6] In July 2008, Lexico Publishing Group, LLC, was acquired by Ask.com, an IAC company,[7] and renamed Dictionary.com, LLC.[8] In 2018, IAC sold Dictionary.com and Thesaurus.com to Rock Holdings.[9] At the time of the sale, Dictionary.com was the 447th most trafficked website in the United States, according to the website tracking service SimilarWeb.[9] In 2015, they estimated that there are 5.5 billion word searches a year on its site.[10]

Features and services

Among its features, Dictionary.com offers a Word of the Day,[11] a crossword solver,[12] and a pop culture dictionary[13] that includes emoji and slang sections.

In 2010, Dictionary.com began a Word of the Year feature with the word 'change'.[14] The selection is based on search trends on the site throughout the year and the news events that drive them.[15] Dictionary.com's words of the year have been:[14]

In April 2009, they launched an app on the App Store allowing users to find definitions and synonyms. It also included audio pronunciations, alphabetical indexing, and synonym example sentences.[17] Since then, Dictionary.com released a standalone thesaurus app called Thesaurus Rex along with education apps, Dictionary.com Flashcards, Word Dynamo, and Learning to Read with Zoo Animals.

In early 2020, in response to COVID-19 quarantine home-schooling needs, Dictionary.com launched an interactive platform for learning at home, and an online tutoring service.[18] Later that year Dictionary.com's sister site, Thesaurus.com, launched a writing assistant and grammar checker called Grammar Check.[19] The coronavirus outbreak led to the addition of novel words to the main dictionary (e.g., fomites) and the slang dictionary (e.g., 'rona').[20]
