Abstract
Sibawayehs book is considered the most important book in
the history of Arabic grammatical theory. Researchers in Arabic
sciences cannot help but refer to it. Old linguists could not have
done with out it in their studies and references.
Due to the large number of scholars who have transmitted it,
the text has been subjected to change and corruption.
Undoubtedly, there has been a great effort behind its editing
and verification by I-Iaroun. However, I have found some
alteration and deviation or forced insertion or shortage, thus
causing some of the original material of the text (in the footnotes).
This confusion leads, in many areas, to the destruction of
rules the inversion of content as well as the correction of mistakes
or in correction of correct material. This has greatly affected some
grammatical, morphological and lexical orientations. This study,
therefore, comes to show areas of confusion correcting them, and
explaining some issues which needed illustration and clarification
the study also addressed a number of areas of ambiguity
which confused important researchers to the extent that they
could not find correct things in them.
