I've found a new favourite site with a dictionary as well as a thesaurus. It's called Mcmillan Dictionay and it's the thesaurus that's making me all exited. It explains the context of the use of the word. It's great for someone like me that are looking for words to extend my vocabulary with. Someone that's also very likely to use the wrong word now and then because it seemed good but did not mean exactly what it seemed to be.
I'll still be using it together with other thesauruses and dictionaries to make sure I get the whole picture, but it's nice to find something new that's also helpful. =)
