kupujcym
Kupującym is the instrumental singular form of the Polish present active participle kupujący, which derives from the verb kupować (to buy) or kupić (to purchase). The participle kupujący commonly functions as a noun meaning “the buyer” or “the purchaser,” especially in commercial and legal contexts. In ordinary language it appears with standard adjective-like declension, and the instrumental singular form is kupującym. The form is used after prepositions that require the instrumental case, most notably after z, in phrases such as z kupującym (with the buyer) or w umowie z kupującym (in an agreement with the buyer).
In formal documents, kupujący is often treated as a party-designator and may be capitalized as Kupujący to
Common usage illustrates its role as both a descriptive term and a legal-designator:
- Umowa z Kupującym została podpisana.
