nevidatelné

Nevidatelné is a Czech adjective meaning not visible to the eye; it is used to describe objects, phenomena or concepts that cannot be perceived visually, either because they lie outside the range of human vision, are concealed, or remain hidden from view.

Form and usage: The word is formed from the verb vidět (to see) with the negative prefix ne- and the adjectival ending -elné, producing neviditelné for neuter singular, and corresponding forms for other genders and numbers (neviditelný, neviditelná, neviditelné). The noun neviditelnost denotes the state of invisibility.

Contexts: In science and technology, neviditelné often refers to wavelengths outside the visible spectrum (such as infrared or ultraviolet) or to invisibility effects in optics. In everyday language, it can describe camouflaged objects or hidden processes, for example neviditelný inkoust or neviditelné vrstvy. The phrase neviditelné síly or neviditelná ruka trhu can appear in philosophical or economic contexts to denote unseen forces shaping outcomes.

Related terms: The concept is closely connected with neviditelnost (invisibility) and opposite with viditelnost (visibility). The word is used across everyday language, science and literature to distinguish what can be perceived from what remains hidden.
