widzialne

Widzialne is a Polish adjective meaning "visible" or "able to be seen." It describes objects, phenomena, or conditions that can be perceived by the eye or by human sensors. In everyday language the term is often paired with negation (niewidzialne) to distinguish what can be seen from what cannot.

In Polish grammar widzialny has several forms: widzialny (masculine singular), widzialna (feminine singular), and widzialne (neuter singular and plural). The masculine personal plural is widzialni. The form widzialne is common in phrases such as "to jest widzialne" (this is visible) or "widzialne rzeczy" (visible things).

In science and technical language the adjective appears in compounds and phrases such as "światło widzialne" or "zakres widzialny," referring to light within the visible portion of the electromagnetic spectrum. Here the term signals perceptibility to human vision rather than non-visual detection.

Origin and related forms: widzialne derives from widzieć, "to see," with the adjectival suffix -alny. The root is common across Slavic languages, with cognates in Russian vidimyy and Czech viditelný. The form widzialne marks neuter singular and plural feminine, while other masculine forms follow standard agreement patterns.

See also: niewidzialny (invisible) and widoczny (visible or noticeable), which have related but distinct usage in Polish.
