this is one great link to better understand our classical al qur'an language (lughaatul qur'an.)
http://www.studyquran.org/ArabicDictionaries.htm
yeah, the page might look a bit unattractive and plain, but if you can check out "Lughaat Al Qur'an - by G.A. Parwez (English translation: Word document or PDF document)",
(2nd line from the top, you'd find some interesting meanings and information iAllah.)
please please PLEASE take some time to read=)))))
If the whole of mankind and the jinn were to gather together to produce the like of this Qur'an, they could not produce the like thereof, even if they backed each other up. (17:88)
