Which dictionary are you using? (English-English dictionary)
Well, Although I know many useful and helpful dictionaries, like OALD, OAAD, Merriam-Webster....etc.
I'm using OAAD (Oxford) now, its explanation is clearly and easily understand but simplified explanations without synonyms makes some of them all look similar, :(
But I'd like to know which one are you using?
Please tell me are you native-speaker or not, currently using which one or which one do you wanna recommend.
thank you. :))

Answer

If you need a good monolingual dictionary with synonyms, I would recommend you this one: http://dictionary.reference.com/.
I also use Macmillan Dictionary http://www.macmillandictionary.com/
