Where does substantive collide?

In traditional grammar a substantive is a noun, a word naming a person, place, thing, or idea, often paired with the adjective as the two halves of the older combined category. Jespersen's The Philosophy of Grammar discusses substantives and adjectives and the criteria that distinguish them. The referent is a part-of-speech category; it shares only the word with a dye's affinity or a branch of law.[1]

Decided by grammatical behaviour, such as inflection, syntactic role, and distribution

In law, substantive law is the body of rules that creates, defines, and governs rights, duties, and liabilities, what the law actually requires, as opposed to procedural law, which governs how those rights are enforced through the courts. Black's Law Dictionary draws exactly this contrast between substantive and procedural law. The referent is a category of legal rules; it has nothing to do with dye affinity or grammatical nouns beyond the shared adjective 'substantive'.[4][2]

In dyeing, substantivity is the affinity a dye has for a fibre directly from the dyebath, without a mordant or a chemical reaction, the property that lets 'substantive' (direct) dyes exhaust onto cotton on their own. Burkinshaw's Theoretical Aspects of Textile Coloration frames substantivity through the dye-to-fibre attraction that drives uptake and governs wash-fastness. The referent is a physico-chemical affinity, sharing only its root with substantive law or the grammarian's substantive.[3]

Unit

The strength of a dye's direct affinity for the fibre

Recovery means

Not applicable

Measured by

Inferred from exhaustion and from the dye's distribution between liquor and fibre
