Operowych
Operowych is a Polish adjective form derived from operowy, meaning "operatic" or relating to opera. It is not a standalone noun, but a grammatical form used to modify nouns in certain cases. Specifically, operowych is the genitive plural form of operowy, and also the locative plural form after prepositions that govern the locative. The form occurs in phrases describing things connected with opera, especially in arts and music contexts. Examples: utworów operowych (operatic works), aktorów operowych (opera actors/performers), scen operowych (opera stages/scenes), światów operowych (worlds of opera). The sense is determined by the noun it accompanies: it signals a relation to opera rather than to other senses of "oper-" in technical fields.
Origins and use: The stem comes from opera, the Italian-influenced term adopted into Polish; the suffix -owy
