zapalnych

Zapalnych is a grammatical form of the Polish adjective zapalny, meaning flammable or easily ignited. Specifically, zapalnych is the genitive plural form (and, in many contexts, the accusative plural for masculine personal nouns) and is used when describing nouns in those cases. The form appears in contexts where the noun is plural and in a case that requires the ending -nych.

Grammatical use

- Genitive plural: zapalnych modifies masculine, feminine, or neuter nouns when they appear in the genitive plural. This occurs in phrases such as “substancji zapalnych,” meaning “of flammable substances.”

- Instrumental plural: zapalnymi is the instrumental plural form, used with nouns in the instrumental case, e.g., “substancjami zapalnymi,” meaning “with flammable substances.” In this construction the adjective ending changes to zapalnymi, while zapalnych remains the genitive form.

- Distinction in common phrases: in nominative plural, feminine or neuter nouns typically take zapalne (e.g., substancje zapalne = flammable substances), while masculine personal nominative plural uses zapalni.

Common usage

- In safety, regulatory, and technical language, zapalny and its forms are used to classify materials and conditions. The phrase substancje zapalne is common for “flammable substances.” Synonyms such as łatwopalny are also used in safety labeling, though usage depends on regional or organizational standards.

Notes

- The form zapalnych should be interpreted in context, as it signals genitive plural (and sometimes accusative plural) rather than being a standalone noun. It is part of a broader system of Polish adjective declension that varies with gender, number, and case.
