History[edit]

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] In 2024, Rock Holdings sold Dictionary.com and Thesaurus.com to IXL Learning.[11]

In April 2009, they launched an app on the Apple App Store allowing users to find definitions and synonyms. It also included audio pronunciations, alphabetical indexing, and synonym example sentences.[19] 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.[20] Later that year Dictionary.com's sister site, Thesaurus.com, launched a writing assistant and grammar checker called Grammar Coach.[21] The coronavirus outbreak led to the addition of novel words to the main dictionary (e.g., fomite) and the slang dictionary (e.g., rona).[22]
