liukoisista

Liukoisista is a Finnish grammatical form: the elative plural of the adjective liukoisa, meaning soluble. It appears in phrases that describe substances or groups of substances that are soluble. Because it agrees with a plural noun in the elative case, it translates roughly as “from soluble [things]” or “of soluble [things]” in English. The most common noun phrases are liukoisista yhdisteistä (from soluble compounds) or liukoisista aineista (from soluble substances).

Usage and meaning: In chemistry, pharmacology, and environmental science, liukoisa is used to distinguish substances that dissolve in a given solvent from those that do not (the latter may be described as insoluble or non-liukoinen in context). The related noun liukoisuus denotes solubility, the property of a substance to dissolve. Finnish technical writing often contrasts soluble substances with insoluble forms, such as liukeneva/aineet and liukenemattomat, depending on the context.

Grammar note: As an adjective, liukoisa declines to match case and number. In the elative plural, it becomes liukoisista. This form is used when the modifier describes a plural noun in contexts like “from soluble substances” or “of soluble compounds.” The construction is common in scientific Finnish but not a separate lexical item beyond its grammatical function.
