Arabic grammarians traditionally divide the language into only three categories:
Kasra (i) for (After prepositions or in possession) VI. The Iḍāfa Construction
By applying different vocalic patterns and prefixes/suffixes, the root transforms into specific words: Kataba (He wrote) Kitāb (A book) Maktaba (A library/office) Kātib (A writer) III. Parts of Speech
The Iḍāfa (annexation) is the primary way to express or relationship between nouns. It places two nouns side-by-side (e.g., Sayyārat al-rajul – "The car of the man"). The first noun never takes a definite article, as its definiteness is determined by the second noun. VII. Conclusion
