When the user highlights a word or phrase while reading an article, the app will pop up a (non-modal) window that contains a definition of the word from Wiktionary.

Goal Visibility

Reading internal goal.


Taking an example from link previews (which are useful for providing a quick definition of linked articles), this will provide a convenient definition of any highlighted word, without the need for the user to leave the app to look the word up. This will also provide a good example of cross-wiki-project integration, considering that Wiktionary content will be integrated seamlessly in a primarily-Wikipedia product.

Success Metrics

External Dependencies

This depends on the robustness of the existing Wiktionary API, and any deficiencies in this API to be addressed before work on this task is completed.


It's not yet certain whether the app will interface with the Wiktionary API directly, or if the app will only query the Content Service which will interface with Wiktionary itself.

Product Plan


Prototypes to be provided by Design.


The Wiktionary definition window should contain a concise definition of the highlighted word or phrase. Ideally this should be rendered natively (without the need for a WebView).
