W/Salam,

Cant u find definitions from Wikipedia? It almost worked for me, i simply write 'Definition' by wikipedia and it's there or sometimes wikianswers. or simply put question mark after the word (definition) in google search and find. I hope it will work, or i wonder may be i Didn't understand your question properly.
