Etymology: In chemistry, "hydrate" was a coinage built from Greek "hydōr", meaning water, which is also the root of "hydra", the many-headed water serpent, and shares an ancient ancestry with English "water". A hydrate is a compound that has taken up water into its structure, as in crystals of copper sulfate that hold water molecules. "Hydrative" is formed by adding the suffix "-ive", meaning "tending to" or "relating to", to that verb-based stem, so it describes what causes or involves such water uptake. The suffix does the work here. "-ive" was added to Latin-derived roots to make adjectives of tendency or function, as in "active" or "creative", and English speakers have applied it freely to scientific stems. Because "hydrative" is a technical formation rather than an old everyday word, it is mainly found in specialist writing on chemistry, biology, and materials science, and its exact date of first use is uncertain.
