Google Dictionary for Chrome allows the in-browser search for the meanings of words.
This extension permits you to view the complete definition of any word or phrase using the toolbar dictionary. It can also store a history of words you've looked up, allowing you to look them back up at a later time.
Google Dictionary for Chrome also provides you with definitions for words you select or double-click.
Supported dictionaries:
- Arabic - Brazilian Portuguese - Chinese (Simplified) - Chinese (Traditional) - Czech - Dutch - English (UK) - English (US) - French - German - Hindi - Italian - Japanese - Korean - Russian - Slovak - Spanish - Turkish
If you opt-in (via the options page), this extension will store a history of all your looked-up words and their definitions. You can download this history as a CSV file at any time. Also, you can allow other Chrome extensions to access this history. For example, a third-party extension could produce flashcards to help you practice words you've looked up before.
G App Launcher for Chrome and Firefox gives you the option to create a menu that stores all your Google service shortcuts (1000+), allowing fast access to frequently used ones.
