ukázkou

Ukázkou is the instrumental singular form of the Czech noun ukázka, meaning an example, a demonstration, or a specimen. It denotes something presented to illustrate a point or to serve as a model in teaching, evaluation, or communication. The term can refer to a concrete physical specimen as well as an abstract demonstration of a method or procedure.

Etymology and grammar: ukázka comes from the verb ukázat, “to show.” The suffix -ka forms a noun meaning a thing shown or demonstrated. The instrumental form ukázkou is used in constructions such as “je ukázkou toho, …” or “na ukázku,” indicating that something is being shown or offered for demonstration.

Usage and phrases: Common expressions include “jako ukázkou,” “na ukázku,” or “ukázkou toho, jak ….” In sentences, it often functions to highlight that an instance is representative or instructive. In formal writing, ukázkou can introduce a specimen in a catalog, a manual, or a report, signaling that the following material is intended to illustrate a point.

Examples:

- Toto je ukázkou toho, jak funguje nový software.

- Na ukázku předvedli několik klíčových kroků postupu.

Notes: Ukázkou emphasizes illustration or demonstration and is used across everyday language and formal prose. The nuance is tied to the instrumental case and the context of presenting an example rather than merely naming one.
