roztokové

Roztoková is a Czech term that can function as a feminine adjective and, in some cases, as a surname form. It is derived from roztok, meaning “solution,” with the gendered adjectival suffix -ová, which in Czech marks feminine form and is also used to form feminine surnames from masculine bases.

As an adjective, roztoková denotes a relation to a solution. It is chiefly used in technical or scientific contexts and appears in compounds describing properties, processes, or materials associated with solutions. In practice, however, many phrases referring to a solution are more commonly expressed with word order that centers on roztok or a noun describing the substance, for example teplota roztoku (the temperature of the solution) or koncentrace roztoku (the concentration of the solution). The exact collocations can vary by field and style guide, and some usages may feel archaic or context-specific.

In addition to its adjectival use, roztoková is also encountered as a feminine surname form in Czech naming conventions. As with many Czech feminine surnames, it marks a female bearer of a family name derived from a masculine form, though specific masculine equivalents depend on the family lineage and origin of the surname.

Summary: roztoková is a gendered Czech form linked to the concept of a solution, used primarily in technical language, and also appearing as a feminine surname in Czech and related naming practices.
