odpornego

Odpornego is a declined form of the Polish adjective odpor‑ny, which means resistant, durable, or immune. The base form odpor‑ny is used for masculine singular subjects in the nominative case; odpornego appears in the genitive singular masculine and, in contexts involving masculine animate nouns, in the accusative singular. In other gender and number forms, the adjective turns into odpowiednie forms such as odporna (feminine singular), odporne (neuter singular or plural).

Etymology and related forms: The word odporny derives from the root odpor- meaning resistance, with the common Polish adjectival suffix -ny. It is cognate with similar Slavic forms expressing durability or immune qualities. Related nouns include odporność (resistance, immunity) and phrases such as odporować or odporność in various older or technical registers.

Usage: Odpornego is most often encountered in contexts where the modified noun is masculine singular and in the genitive case, for example after certain verbs or determiners that govern genitive. Examples include negations or phrases describing the lack of resilience: Nie ma materiału odpornego na korozję (There is no material resistant to corrosion). Another example is Brak systemu odpornego na ataki (Lack of a system resistant to attacks). In standard, present-tense statements about a resistant property, the base form odporny or its feminine/neuter/plural equivalents are typically used, e.g., materiał odporny na kwas (a material resistant to acid).

Notes: Odpornego is not a standalone predicate form; it functions as a grammatical case form within noun phrases. Its usage helps express possession, negation, or description when the parameter of resistance is tied to a masculine singular noun in genitive.
