Cambridge Dictionary Chrome extension

All-in-One Cambridge Dictionary lets you look up words on any webpage without leaving the page, through a popup, right-click menu, hotkey, or floating icon, and it draws on more than 30 Cambridge dictionaries. It's best for readers, writers, and language learners who want quick definitions in context. The catch: it depends on Cambridge's own dictionary data rather than a broader general-purpose source.

What Cambridge Dictionary extension does

This extension lets you check a word's meaning while you're reading, without opening a new tab or typing into a search engine. Select or double-click a word and a definition from Cambridge's dictionaries appears in a popup. You can also trigger lookups through a right-click menu, a hotkey, or a floating icon, drawing on more than 30 Cambridge dictionaries covering different languages and specialties.

Cambridge Dictionary extension: free access

The extension itself is free to install and use for looking up words on any website. It's built around Cambridge's own dictionary content, so the range of definitions and translations reflects what Cambridge publishes rather than a combined index of multiple dictionary providers.

Is the Cambridge Dictionary extension safe?

Like other in-page lookup tools, it needs to read the text on pages you visit so it can detect the word you've selected and show a definition. That access is what lets popup and hotkey lookups work on any site you're browsing.
