Suppose Zayd is Amr’s father. Two descriptions arise:
Zayd → father of Amr
Amr → son of Zayd
Different expressions describe the same relationship from opposite ends, illustrating relation.
By contrast, “Zayd is white” states a quality, not a reciprocal relation like father and son. The mere grammatical presence of “of” or “to” does not always prove that the philosophical category of relation is being used.
