rekonstrukcyjnych

Rekonstrukcyjnych is a Polish adjective form that means related to reconstruction or reconstructive. It is the genitive plural (and corresponding accusative plural) form of the basic adjective rekonstrukcyjny. The base noun from which it derives is rekonstrukcja, reconstruction, and the suffix -cyjny yields adjectives indicating pertaining to or characteristic of the root concept.

In practical usage, rekonstrukcyjnych appears when describing plural nouns in the genitive or accusative case. For example: koszty rekonstrukcyjnych materiałów (costs of reconstruction materials), projekty rekonstrukcyjnych prac (projects of reconstruction works), zastosowania rekonstrukcyjnych technik (applications of reconstructive techniques). These phrases commonly occur in fields such as architecture and heritage restoration, medicine and surgery, archaeology, and data or software reconstruction contexts, where processes, methods, or materials are discussed in relation to reconstruction.

Grammatically, rekonstrukcyjnych is the plural genitive form of rekonstrukcyjny, and thus is used with nouns in the genitive plural or with other nouns that require an accompanying genitive plural. It can also appear in contexts where the accusative plural is used, since Polish distinguishes cases for adjectives agreeing with plural nouns. In contrast, other case forms of the adjective (such as rekonstrukcyjny in masculine singular or rekonstrukcyjna in feminine singular) are used in different syntactic positions.
