prokázal

Prokázal is the masculine singular past tense form of the Czech verb prokázat, meaning to prove or demonstrate something by providing evidence or argument. The term is used when a statement, claim, or fact is shown to be true through evidence, reasoning, or official procedures. It is common in legal, scientific, academic, and journalistic contexts, as well as in everyday language when someone presents proof or justification for a claim.

In usage, prokázat implies an active demonstration of truth or validity, often requiring supporting materials, data, or testimony. For example, a court may prokázat a guilt by presenting evidence, a study may prokázat a hypothesis, and a witness may prokázat the accuracy of a report. It is somewhat more formal or precise than simply showing something, and is frequently paired with nouns like důkazy, vinu, platnost, or nárok.

Grammatically, prokázal is the masculine singular past form; other gender and number forms exist: prokázala (feminine singular), prokázalo (neuter singular), prokázali (masculine plural). The infinitive is prokázat. In broader use, the verb is related to confirming or substantiating claims, and is widely encountered in formal writing and discourse.
