a semantic relation between two objects, prototypically ownership, but also including weaker relations such as temporary ownership and physical contiguity. Example: in I have a pen, there is a possession relation between myself and the pen – I am the possessor and the pen is the possessum. This possession relation could be full ownership, temporary ownership (someone lent it to me), or physical contiguity (I have a pen at hand). Other object–object relations such as body parts, part–whole, and kinship are generally also included under possession relations. (Section 10.4.2)
