Koupí

Koupí is a Czech term that can refer to two related, but distinct, linguistic items: the noun koupě and the verb form koupí of koupit. The noun koupě means the act or result of purchasing something; a purchase or acquisition. It is used in formal, legal, or business contexts to describe a transaction or the item bought, for example koupě bytu (purchase of an apartment) or cena koupě. In everyday speech, people often use nákup to mean shopping, but koupě stresses the act or agreement involved in acquiring something.

As a verb form, koupí is the third-person singular of koupit and represents a future action (he will buy) rather than a present one, because Czech perfective verbs form the future this way. It can be used with or without a reflexive pronoun: on koupí si auto (he will buy himself a car) or on koupí auto (he will buy a car). Examples: Zítra koupí nové auto. Koupí si nový dům.

The two forms are distinguished by meaning, spelling, and pronunciation, and they appear in different syntactic contexts. They should not be confused with similar-sounding words such as koupe, which comes from the verb koupat and means a bath or bathing, and is not related to purchase. Overall, koupí functions as a verb form indicating a future purchase, while koupě denotes the act or result of buying.
