Tatoeba
Tatoeba.org is a free collaborative online database of example sentences geared towards foreign language learners. Its name comes from the Japanese term "tatoeba" (δΎγγ°γtatoeba), 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.
