The grammar section of the App provides a set of guidelines for annotators who wish to contribute to the project. In the Quranic Arabic Corpus, the traditional Arabic grammar of iʿrāb (إعراب) is used to visualize Quranic syntax through the use of dependency graphs. This description of Quranic grammar is useful for further computational analysis, as well as for linguists researching the language of the Quran, and for those with a general interest in the Arabic language. The syntactic treebank contains verses of the Quran annotated using dependency grammar.
