The word 'determinable' is a correct and usable word in written English.
You can use the word 'determinable' to describe something that can be determined or concluded after evaluation or investigation. For example: After careful inspection, it was determined that the cause of the accident was a determinable mechanical failure.
After all, the only non-logical predicates in ψ are 'L' for the exact location relation and 'P' for the parthood relation, it's plausible that both relations are fundamental, and they do not seem to be related as determinate to determinable or as determinates of the same determinable.
In the Meno (74ff), Plato develops the notion of determinable and determinate.
But Kant thinks that it is also possible to interpret predication in the reverse direction: that is, from "determinate" to "determinable".
Matter is a determinable made determinate by form.
For example, Yablo (1992), suggests that mental and physical properties stand in the relation of determinable and determinate (just as red stands to scarlet), and argues that our conviction that a cause should be commensurate with its effects permits us to take the determinable, rather than the determinate, property to count as causally efficacious in psychological explanation.
Absolute nothingness is infinitely determinable and its determinates form the actual world, but this "self-determination" occurs "without anything that does the determining," like an agency without an agent.
Similarly, rest mass and rest mass of 3 kilograms are a determinable and a determinate, respectively.
How does this definition fare for our paradigm, 'F (red) is a determinate falling under determinable G (colored)'? Clause (3) requires that every Boolean part of the property red implies the property of being colored.
Her discussion focuses on a group of metaphysical relations what she calls the 'small-g' grounding relations that include token identity, realization, the classical extensional part-whole relation, the set membership relation, the proper subset relation, and the determinable-determinate relation.
Consider the determinable-determinate relation and the Aristotelian genus-species relation, two relations that are presumably among those that the proponent of the argument thinks that the grounding relation unifies.
Zimmerman's formulation does not repair a difficulty in Searle's, namely, that the red-colored paradigm fails to satisfy the definition of the determinate-determinable relation.
