The quality or state of being able to be diminished or reduced.
Compound of 'diminishable' and the suffix '-ness,' which converts adjectives to abstract nouns. This creates a noun describing the property of being reducible, following standard English word-formation patterns.
This is the kind of word philosophers love because it asks: what is the fundamental 'ness' or property that allows something to shrink? It's beautiful, unwieldy, and exactly the sort of thing 18th-century thinkers debated!
