Relative pronouns in Arabic grammar are essential for connecting clauses and sentences to create more complex and nuanced statements. They serve to relate a noun to an action and create a relationship between the subjects within a sentence. In Arabic, the relative pronoun “الذي” and its variants (الذين, التي, and اللاتي) vary depending on the gender and plurality of the noun they are modifying. Mastering relative pronouns in Arabic is important for achieving a more advanced level of proficiency and improving overall communication skills.
