Wielki słownik

Discover the world's most comprehensive and up-to-date English-Polish dictionary. With an impressive 3.3 million words, covering hundreds of thousands of meanings across over 200,000 definitions, our dictionary surpasses the scope of previously published dictionaries by more than 20%.



But it's not just the sheer number of entries that sets this project apart. Our dictionary stands out with its specialized vocabulary from over 150 fields, particularly in business and finance. Thanks to the collaboration with renowned expert Roman Kozierkiewicz, our dictionary is not only the largest but also the most comprehensive.


Our dictionary is the only major English-Polish dictionary that includes 21st-century vocabulary. We have strived to maintain a balance between British and American English, while also considering other variants of the English language to a certain extent. We have treated British English, which is also the official language of the European Union, as the primary variant.


Our dictionary is not only gigantic but also dynamic. Its resources will be continuously developed and expanded. We plan to further work on this dictionary, and future versions will be available free of charge to all new purchasers from the App Store.


The dictionary is an application that operates entirely on the user's device and does not require an internet connection for normal operation (data is stored within the app). Users can anonymously report comments and errors to the dictionary, but no data about them is recorded.
