Lately, the Swiss news portal Watson.ch released an article about the 15 most useful websites everybody should know. Canoo.net, the online language service for German language and grammar, was one of the recommendations of the Watson.ch readers.
Canoo.net is a free-of-charge service which brings you information concerning the proper usage of standard German. But it is far more than just another dictionary – the platform delivers valuable info about spelling, synonyms, broader and narrower terms, antonyms, etc.
Canoo.net is also available as iOS-App.
