1911 Encyclopædia Britannica/Adjective

ADJECTIVE (from the Lat. adjectivus, added), a word used chiefly in its grammatical sense of limiting or defining the noun to which it refers. Formerly grammarians used not to separate a noun from its adjective, or attribute, but spoke of them together as a noun-adjective. In the art of dyeing, certain colours are known as adjective colours, as they require mixing with some basis to render them permanent. "Adjective law" is that which relates to the forms of procedure, as opposed to "substantive law," the rules of right administered by a court.
