demonstruje

Demonstruje is the third-person singular present tense form of the Polish verb demonstrować (also demonstruować), meaning to demonstrate, show, or illustrate. The form is used for he, she, or it demonstrates. In Polish, the present tense conjugation follows regular patterns, so the full present tense forms include ja demonstruję, ty demonstrujesz, on demonstruje, my demonstrujemy, wy demonstrujecie, oni demonstrują.

Etymology and usage context

The verb derives from Latin demonstrare and related Romance forms such as French démontrer, transmitted to Polish through historical scientific and scholarly language. In contemporary Polish, demonstrować is common in both everyday and technical contexts. Demonstruje, as a present-tense form, appears in academic writing, journalism, and public discourse to indicate that a claim, method, or example is being shown or proven. It can also appear in more literal senses, such as demonstrating a procedure or device.

Ambiguity and nuances

Demonstruje can express logical demonstration (proving a point or illustrating a result) as well as practical demonstration (displaying how something works). In certain contexts, other verbs such as pokazać or demonstrować may be used interchangeably, but demonstruje specifically marks a present action by a singular subject.

Examples

- On demonstruje, że twierdzenie jest prawdziwe. (He demonstrates that the theorem is true.)
