La Critique du Language. Kanz al-Huffaz fi Kitab Tahzib al-Alfaz. كنز الحفاظ في كتاب تهذيب الألفاظ

Ibn as-Sakkit of Baghdad, the acknowledged scholar of lexicography and syntax, was the tutor of Mutawakkil’s son. “Although he is mostly counted among the Kufan grammarians, he received his professional education in Baghdad, where his teachers were, among others, al-Fraa’, Qutrub, abu ‘Obaida andal-Asma’i.
Most of ibn as-Sakkit’s work has not been preserved, but his influence must have been considerable in view of the fact that he is extensively quoted by almost all later lexicographers. His main interests were poetry and lexicography, but it is important to note that in his most important lexicographical work, the Kitab Islah al-Mantiq, he arranged his material at least in part according to morphological criteria.” Lexicon Grammaticorum, p. 695.
