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.

[7] In 2014, OUP launched Oxford Global Languages, an initiative to build lexical resources (bilingual dictionaries) of the world's languages, starting with Zulu and Northern Sotho online dictionaries released in 2015.

A statement from OUP said, "Rather than offering a dictionary website for every digitally under-resourced language, we will facilitate third parties to build products and services that best serve the needs of each individual language community.

"[14] At the time of the closure, they hosted dictionaries of Zulu, Northern Sotho, Malay, Urdu, Tswana, Indonesian, Romanian, Latvian, Swahili, Hindi, Tamil, Gujarati, Tatar, Xhosa, Southern Quechua, Tajik, Tok Pisin, Turkmen, Telugu, and Greek.

The OED, on the other hand, is a historical dictionary and it forms a record of all the core words and meanings in English over more than 1,000 years, from Old English to the present day, and including many obsolete and historical terms.
