In the course of a recent study (a thesis on Abū-l-‘Alā’ as a poet), I have come upon certain words in Luzūm mā la- Yalzam which, to the best of my knowledge, do not occur in Ibn Durayd's Jamharah, Al-Asās, al-Ṣiḥāḥ, al-Qāmūs, al-Mukhaṣṣaṣ, Täj al-'Arūs, Lisān al-'Arab, al-Jāsūs ‘ala-l-Qāmūs, Lane's Lexicon, or al-Munjid. It might be interesting, from the point of view of Arabic philology, to examine some of these rare words here, if only because they occur in the work of such a distinguished authority as Abū-l-‘Alā’. I have consulted the texts in which these words occur in the Cairo edition of the Luzūm, the Bombay edition, and the British Museum MS., Or. 3160.
