In the third type the point is not just the idea of a quality. It is the attribution of that quality to a particular person. The speaker may locate the quality in a place or object strongly associated with the intended individual.
For instance, generosity may be described as residing in someone’s tent or household.
The tent is not literally a generous agent. The rhetorical construction directs the quality toward its intended possessor by placing it within the sphere identified with that person.
