The "VoyCabulary" site lets you add automatic (point and click) dictionary (English or English - German) look-up to all the words in any web page you are reading!
Rhyming dictionary, this is not just fun stuff or help for writing poetry, it's a good site to find a word you're not sure how to spell. The results appear grouped according to the number of syllables they contain. Instead of rhymes, you can search for homophones, similar sounding words, similar spellings or related words. Ans Me does the same and will automatically look for similar sounding words if it doesn't recognise the word you enter.
