تَقُولُ: «جَاءَنِي أَخُوكَ، وَرَأَيْتُ أَخَاكَ، وَمَرَرْتُ بِأَخِيكَ»، وَكَذَا الْبَوَاقِي.
Translation: You say: “Your brother came to me; I saw your brother; and I passed by your brother.” The remaining nouns follow the same pattern.
أَخُوكَ uses wāw, أَخَاكَ uses alif, and أَخِيكَ uses yāʾ as case signs. The final pronoun كَ is unchanged.
