Babylonary
Read full descriptionHide full description
Babylonary is an app for consulting the online dictionary "wiktionary.org". Wiktionary is available in many different language versions: For example, "de.wiktionary.org" exists as a German version or "en.wiktionary.org" exists as an English version. Each of these versions tries to be a dictionary of all languages of the world in its own language. However, the individual versions are very different in scope, so that the information is different or often not available at all. Therefore, Babylonary allows you to query several Wiktionary versions simultaneously, i.e. in your native language and in foreign languages that you understand. You can specify the Wiktionary versions to be queried under "Select languages". This app is freeware. It comes with absolutely no warranty. Use it at your own risk!
