Lingopolo is based on the idea of Comprehensible Input presented in an interactive way. Comprehensible Input is basically learning language from hearing (or reading) material which is just a teeny bit above your current level, so that you can understand it, and new words or sentence structures in the material can be learnt indirectly from context.

There are some great websites which take this concept of Comprehensible Input very seriously, by containing videos in the target language from beginner to advanced.

Wherever possible, every word has examples of its use in phrases. Each of these phrases are also in Lingopolo, so you can click on the phrase to browse in more detail, or click on the Learn button to practice just that phrase.
