Definition: The expression (g PROPR r)
is used to characterize a plurality g
by means of a semantically relational quality r
.
Examples:
The bids were comparable.
Notes:
“The bids were comparable” doesn't mean that each of them was comparable on its own. “Comparable” makes sense only in the context of the whole collection, cf.:
The bids were low.
In this example the proper relation to use is PROP.
