Annual updates
Language is constantly evolving, meaning our datasets are, too. Our annual product updates see a number of our key datasets updated with a great deal of new material and updated or revised targeted entries as part of our ongoing work to ensure that our content is fresh, contemporary, and appropriate for all users.
Based on evidence gathered by our expert lexicographers, our annual updates include new definitions, headwords, phrases, senses, and global varieties, as well as editorial reviews, updates, corrections, and sensitivity reviews.
Keep your products contemporary with annual updates from Oxford Languages.
