Cambridge Dictionaries Online is another great tool for the language learner. Choose between British English, American English, Business English, English-Spanish, Spanish-English and English-Turkish dictionaries. There is a great thesaurus, a blog and a word of the day section. A great advantage the Cambridge dictionaries offer is the topic section where words are grouped by themes.
