The Greek Verbal Lemmas from the Lexicon by Bar Bahlul, their Origin and the Lost Work by Hunayn ibn "Ishaq Principles of i''rāb / According to the Greek Scholars"
The present article is an overview of 688 lemmata from the Syriac national dictionary, Lexicon by Isho Bar Bahlul (10<sup>th</sup> century A. D.). These lemmata comprise Syriac transliterations of the Greek finite verbs as well as their translation into the Syriac and Arabic languages. The author argues that these lemmata trace their origin back to those from the Byzantine Greek manual by George Choeroboscus (around the 8<sup>th</sup>-9<sup>th</sup> century A.D.). Their translation into Syriac and Arabic was completed by Hunayn ibn Ishak al-'Ibādl (d. 873 A.D.). The author also argues that these 688 lemmata are in fact the evidences of exercises used by Hunayn ibn Ishaq in his Greek manual (احكام الاعراب على مذهب اليونانيين Aḥkām al-i'rāb 'alâ maḍhab al-yūnāniyyīn), which until recently has been considered to be irrevocably lost.
