Two grammatical forms for attributing a related person's quality

The Predicate as a Single Expression: Causal Linkage, Clauses, Verbs and Nouns

رَجُلٌ كَرِيمٌ أَبُوهُ
A man whose father is generous.

زَيْدٌ أَبُوهُ مُنْطَلِقٌ
Zayd's father is departing.

Both statements predicate a quality or act of a related father rather than the primary noun. Their grammatical forms, however, differ: the former uses a causally linked adjective, while the latter uses an entire nominal clause as Zayd's predicate.
