UN English Programme's List: ELPE Vocabulary

This 'meta-dictionary' allows you to check over 1000 free online dictionaries with one click. If one definition isn't clear, you can check another one. Often there's a chance to listen to the word pronounced. It also features a 'reverse dictionary' that allows you to type in a definition of a word you can't remember. NOTE: If you do this, the 'answer' will come as a long list of words. The word you are looking for will nearly always be one of the first three words - so you can ignore the rest.
