"a smart Arab boy"
Translation:وَلَد عَرَبِيّ ذَكِيّ
As a general rule in most languages, adjectives like colour, material, or nationality tend to stand closest to the noun. In English this means right before the noun because adjectives come before it (smart Arab boy), in Arabic it's the same principle, but in reverse order because adjectives come after the noun. This knowledge really helped me memorizing the preferred order.
