hydratoitujen

hydratoitujen is a Finnish inflected form of the adjective hydratoitunut, meaning hydrated. The base hydratoitunut describes a substance in which water is chemically bound as part of its structure or composition. The form hydratoitujen appears when the adjective modifies a plural noun in grammatical contexts such as the genitive or other cases, indicating possession or attribution (for example, in a phrase referring to “hydrated [substances]” in a plural form). In ordinary speech and writing, hydratoitunut and hydratoituneet are more common in the nominative, while hydratoitujen is used to connect to other elements within a sentence.

The concept behind hydratoitunut is central to chemistry, mineralogy and related sciences. Hydrated substances, or hydrates, contain water molecules within their crystal lattice or as part of their chemical formula. Finnish scientific terminology often distinguishes hydratoituneet mineraalit or hydratoituneet suolat to describe minerals or salts that have been chemically bound with water.

Etymology and related terms: hydratoitunut derives from the verb hydrata- (to hydrate) with the common Finnish past participle suffix -tu- plus -nut-/ -nuton, producing hydratoitunut. The root hyd- traces to the Greek/Latin elements for water (hydro/hydra). Related concepts include hydrataatio (hydration), hydratoituminen (hydration state) and dehydrataatio/dehydratoituminen (dehydration).

Usage notes: hydratoitujen appears primarily in technical or academic Finnish when referring to multiple hydrated substances in a case-marked phrase. In everyday language, speakers more often use hydratoitunut or hydratoituneet in the nominative and mixed contexts.
