About this app

The Good Dictionary explains the 19,000 most important words in the English language — more thoroughly than any other dictionary.

Every entry gives you:
• Clear definitions in plain language, most common meaning first
• The story behind the word: where it came from and how it got its meaning
• Idioms with explanations of what they mean and where they came from
• Guidance on words that are often confused with each other

And it all works completely offline. No internet, no ads, no tracking — just the dictionary, always in your pocket. Perfect for school, exams, travel, and anywhere else your phone must stay in flight mode.

Tap any word inside a definition to jump straight to its own entry, and wander through the English language the way you would browse a good book.

Includes a foreword and an illustrated guide to where English comes from.
