In this book, Dr. Muayyad Saeed presents us with interesting and original research in which he attempts to trace the origins of some of the vocabulary and its meanings contained in classical and colloquial Arabic, especially the colloquial Iraqi dialect in the central and southern regions of modern Iraq, and to trace it back to the languages of our ancestors that were prevalent in Mesopotamia. The ancient language is an interesting and enjoyable material for the Arab and Iraqi reader in particular, to realize that the words he uses in his colloquial dialect to this day are authentic words whose origins go back to the language of his ancient ancestors, the owners of the oldest human civilization in history.
