zinkovým
Zinkovým is a term that appears to be a grammatical form in the Czech language. Specifically, it is the instrumental singular masculine/neuter form of the adjective "zinkový," which translates to "zinc" or "of zinc" in English. This grammatical case is used to indicate the means by which an action is performed or the instrument used. Therefore, "zinkovým" would be used in a sentence to describe something being done with, by, or through something made of zinc. For example, a phrase like "ošetřené zinkovým plechem" would mean "treated with a zinc sheet." The root of the adjective is "zinek," the Czech word for zinc. Zinc is a chemical element with the symbol Zn and atomic number 30. It is a bluish-white metal that is brittle at room temperature but malleable when heated. Zinc is widely used in galvanizing steel to prevent rust, in the production of alloys like brass, and in batteries. The adjective "zinkový" therefore describes anything related to or made of this metal.
