prokazuje

Prokazuje is the third person singular present indicative form of the Czech (and similarly used in Slovak) imperfective verb prokazovat, meaning "to show," "to demonstrate," or "to prove." As a verb form, prokazuje is used to describe an ongoing, habitual, or repeated action: "on/ona/ono prokazuje" — "he/she/it shows or proves."

Grammatical and lexical notes: prokazovat is imperfective; its perfective counterpart is prokázat, whose related future or completed actions use forms like prokáže. Prokazuje appears in declarative sentences, questions, and subordinate clauses where demonstration or evidencing is expressed. It combines the prefix pro- with a root related to showing or indicating, a pattern common in Slavic verb formation.

Usage contexts: The verb form is common in legal, scientific, journalistic, and everyday language. In legal and administrative texts it often denotes evidentiary functions ("dokumenty prokazují" — the documents prove), while in scientific reporting it describes empirical demonstration ("studie prokazuje" — the study demonstrates). In conversation it can describe habitual behavior ("prokazuje trpělivost" — he/she shows patience).

Examples:

- Dokumenty prokazují jeho totožnost. (The documents prove his identity.)

- Studie prokazuje souvislost mezi faktory. (The study demonstrates a link between the factors.)

Etymology: The form derives from the verb prokazovat/prokázat, built from the prefix pro- and a Slavic root meaning to show or indicate.
