pustych

Pustych is primarily a Polish inflected form that arises from the adjective pusty, meaning empty or bare. In Polish it is most often encountered as the genitive plural form of pusty and is also used as the accusative plural for inanimate nouns. It appears in phrases such as pustych miejsc meaning empty places or pustych domów meaning empty houses. The form is thus a grammatical marker rather than a standalone lexical item.

In addition to its grammatical use, Pustych is also found as a Slavic surname. In Polish and Ukrainian contexts the name Pustych (or its transliterations such as Pustykh) may be borne by individuals or families. Surname formation from adjectives is common in Slavic naming traditions, and Pustych likely derives from the same root meaning "empty" or "deserted," potentially describing a geographic feature or a historical occupation.

The root pust- is shared across several Slavic languages, with cognates appearing in Polish pusty, Ukrainian pustyy/pustiy, and Russian pustoy/pustye. These forms reflect related lexical fields centered on absence or emptiness. See also pusty, pustynia, and related toponymic or descriptive surnames in Slavic onomastics.
