Read Tatoeba (en.wikipedia.org)

Tatoeba is a free collaborative online database of example sentences geared towards foreign language learners. Its name comes from the Japanese term "tatoeba" (例えば), meaning "for example". Unlike other online dictionaries, which focus on words, Tatoeba focuses on translation of complete sentences. In addition, the structure of the database and interface emphasize one-to-many relationships. Not only can a sentence have multiple translations within a single language, but its translations into all languages are readily visible, as are indirect translations that involve a chain of stepwise links from one language to another.
