This article discusses theories designed by medieval Arabic grammarians to explain one of the most puzzling topics in Arabic grammar, mamnūʿ min al-ṣarf (diptotes). The mainstream theory of mamnūʿ min al-ṣarf probably took on its definitive form in the early 4th/10th century; it differs from Sībawayhi’s (d. ca 180/796) theory, yet consists of a generalisation of features found in the latter. A later modification, which retained its basic elements, was presented to the mainstream theory probably during the 7th/13th century. A radically different theory was presented by al-Suhaylī (d. 581/1185), who harshly criticised the mainstream theory as inadequate and arbitrary.

“虽然这很疯狂，但其中有方法”：阿拉伯语语法传统中的 mamnūʿ min al-ṣarf（双语词）

本文讨论由中世纪阿拉伯语语法学家设计的理论，用于解释阿拉伯语语法中最令人费解的主题之一，mamnūʿ min al-ṣarf（双语）。mamnūʿ min al-ṣarf 的主流理论可能在 4 世纪/ 10 世纪早期就形成了其确定的形式；它不同于 Sībawayhi (d. ca 180/796) 的理论，但包含后者中特征的概括。后来的修改，保留了其基本要素，可能在 7/13 世纪出现在主流理论中。al-Suhaylī (d. 581/1185) 提出了一个完全不同的理论，他严厉批评主流理论是不充分和武断的。
