Advanced English Dictionary

This is a new collaboration between Dictionary.com and Oxford University Press (OUP) to help users worldwide with everyday language challenges. Lexico is powered by Oxford’s English and Spanish dictionaries and features multi language dictionary, thesaurus, and translation content.

This partnership is exciting but may lead to a few questions, so please look through our frequently-asked questions below for some answers:

1. Are there still Oxford sites?

There are many Oxford sites that are still active, but the free English and Spanish content is now exclusively available through Lexico.


2. How can I switch between the UK and US dictionaries?

When performing a search, select the drop-down menu next to the search bar (or below the search bar on mobile) to select the dictionary you'd like to use. This drop-down menu also allows searches of our grammar articles or the thesaurus. The selector will remember your preference for subsequent searches.

4. Are there different definitions of words in the UK and US English Dictionaries?

Both dictionaries share similar entries and definitions, but there can be differences in terms of pronunciation, spelling, as well as region-specific words and phrases. Some terms have additional definitions in either UK or US English. In addition, you’ll often find different example sentences for each dictionary.

5. Who writes the definitions?

All definitions and translations are written by Oxford lexicographers. You can read how dictionary content is created by visiting Oxford University Press.
