Lexico
dictionary website

Lexico was a dictionary website that provided a collection of English and Spanish dictionaries produced by Oxford University Press (OUP), the publishing house of the University of Oxford. While the dictionary content on Lexico came from OUP, this website was operated by Dictionary.com, whose eponymous website hosts dictionaries by other publishers such as Random House. The website was closed and redirected to Dictionary.com on 26 August 2022.
Before the Lexico site was launched, the Oxford Dictionary of English and New Oxford American Dictionary were hosted by OUP's own website Oxford Dictionaries Online (ODO), later known as Oxford Living Dictionaries. The dictionaries' definitions have also appeared in Google definition search and the Dictionary application on macOS, among others, licensed through the Oxford Dictionaries API.
History
In the 2000s, OUP allowed access to content of the Compact Oxford English Dictionary of Current English on a website called AskOxford.com. In 2010, Oxford Dictionaries Online was launched under oxforddictionaries.com, superseding the dictionary content of AskOxford.com. Buyers of the third edition of the Oxford Dictionary of English, also published in 2010, were granted a one-year subscription to the website's subscription content. The website's English dictionaries incorporated content of the Oxford Dictionary of English, New Oxford American Dictionary, Oxford Thesaurus of English, and Oxford American Writer's Thesaurus. It also provided a Spanish monolingual dictionary and bilingual dictionaries between English and several languages. As of June 2014, it was updated every three months.
This brief starts where responsible research should: with the source description of “Lexico” as dictionary website. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as dictionary website. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q4807054. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2022, 2010 and 2014.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
