Lion is a free 1) Windows application that allows you to translate words by just clicking on them.
Using the popular online dictionary "LEO", Lion offers very comprehensive and powerful dictionaries to translate words from German to English, French, Spanish or Italian and vice versa.
When you found a suitable translation, you can even let Lion type it in for you! A keyboard shortcut further allows you to easily access LEO, whenever you need to type in a word, which translation you don’t yet know.
Lion is absolutely free for private use. That means you can download the software and use it for free, as long as you only install it on private computers and use it non-commercially solely.
If you want to use Lion in a commercial environment, you purchase it for a very reasonable price.
