Margin Dictionary door Leo Proger

Stay curious without losing your place.

Margin Dictionary brings Cambridge English definitions to your reading flow.
Select a word and click Define, use the right-click menu, or press Alt+Shift+D.
The toolbar also lets you look up words manually.

• English definitions and examples
• Parts of speech and British/American pronunciation
• A calm, readable light popup designed for Firefox and Zen
• No account or API key required

Your requested word is sent directly to dictionary.cambridge.org only when you
perform a lookup. Pronunciation audio is requested when you press Play.
No surrounding text, page URL, analytics or persistent query history is sent
to the developer.
