kupní

Kupní is a Czech adjective meaning related to purchase or buying. It is used chiefly in formal or technical language in commerce, finance, and law to describe aspects connected with selling, buying, or the rights and obligations of buyers and sellers.

Common compound terms include kupní cena (purchase price), kupní smlouva (purchase agreement), kupní podmínky (purchase terms), kupní síla (purchasing power), and kupní právo (right of purchase). In real estate, discussions of a transaction often distinguish between kupní smlouva (the contract of sale) and the broader process of koupě nemovitosti (the purchase of property). The term also appears in consumer law contexts and contract law.

Kupní is distinguished from nákupní, which tends to refer more generally to shopping or procurement, whereas kupní is used for formal transactions, contracts, and substantive price or ownership issues.

Etymology and related forms: kupní derives from the noun koupě or the verb koupit (to buy) combined with the suffix -ní to form an adjective. In related languages, such as Slovak, the equivalent term is kúpný.
