Próbne

Próbne is a Polish adjective meaning "trial," "experimental," or "testing," used to indicate that something is not final and is intended for testing or demonstration. It is derived from próba, meaning "trial" or "test," from the verb próbować ("to try").

In usage, próbne describes non-final versions or activities. Common phrases include "próbna wersja oprogramowania" (trial version of software), "próbna produkcja" or "próbna seria" (trial production/run), and "matura próbna" (mock diploma examination). The form "próbne" appears as the neuter singular or as part of fixed expressions; adjectives in Polish agree with the noun they modify.

The term is widely used in education, technology, manufacturing, and research to signal testing phases, quality checks, or preparatory steps before a full-scale release or completion. Related concepts include próba (trial), test, and wersja próbna (trial version).
