kupovati / kupiti (to buy) | Serbian Grammar

Куповати — купити is the basic imperfective–perfective pair for acquiring something in exchange for money. Куповати opens the activity or presents it as habitual; купити presents one purchase as achieved. Both normally take the thing bought in the accusative.

Forms and the -ова- → -уј- stem

The infinitive and past stem of куповати contain -ова-, but its present and imperative use -уј-. This is a productive Serbian conjugation pattern, not a spelling variation.

Form	Imperfective куповати	Perfective купити
present 1sg	купујем	купим
present 2sg	купујеш	купиш
present 3sg	купује	купи
present plural	купујемо, купујете, купују	купимо, купите, купе
past participle	куповао, куповала	купио, купила
imperative	купуј, купујте	купи, купите
Future I	куповаћу	купићу

Обично купујем поврће на пијаци, а хлеб у пекари.

I usually buy vegetables at the market and bread at the bakery.

Купила сам последњу карту преко апликације.

I bought the last ticket through the app. (female speaker)

The first sentence describes a routine; the second asserts one completed acquisition. A perfective present such as купим normally points to a future or conditional boundary: ако купим, “if I buy.” It is not a neutral ongoing present.

💡

Connect the four principal forms: куповати — купујем — куповао — купуј, but купити — купим — купио — купи.

What is bought: accusative

The purchased item is the direct object. Masculine animate nouns therefore take genitive-like accusative, while masculine inanimate nouns retain the nominative form.

Купујемо половни сто за нову канцеларију.

We’re buying a secondhand table for the new office.

Купили су младог пса од регистрованог одгајивача.

They bought a young dog from a registered breeder.

The verb can be used absolutely when the object is understood, especially in a shop: Само гледам, не купујем “I’m just looking; I’m not buying.”

The source is often од + genitive for a person or supplier and у + locative for a shop or other location.

Овај сир купујемо од малог произвођача из Срема.

We buy this cheese from a small producer in Srem.

Лекове је купио у апотеци преко пута болнице.

He bought the medicine at the pharmacy across from the hospital.

Recipient, intended user, and price

A beneficiary can be dative: купити детету јакну means buy the child a jacket. За + accusative profiles whom the item is intended for and can be less tightly integrated: јакна за дете.

Купићу сестри књигу коју је јуче тражила.

I’ll buy my sister the book she asked for yesterday.

Тражимо удобну столицу за деду.

We’re looking for a comfortable chair for Grandpa.

Price can be expressed by за + accusative or as an amount complement. In careful learner production, купити нешто за пет хиљада динара is transparent and reliable.

Ову лампу смо купили за три хиљаде динара на распродаји.

We bought this lamp for three thousand dinars in a sale.

Do not confuse price with payment method. Serbian says платити картицом, with instrumental, while купити картицу means acquire a card.

Object and recipient clitics

Accusative clitics replace a known item: га for a masculine/neuter singular object in relevant paradigms, је/ју for feminine singular, их for plural. With a dative beneficiary, the order is dative before accusative.

Овај ранац је био на снижењу, па сам му га купила за школу.

This backpack was on sale, so I bought it for him for school. (female speaker)

The cluster сам му га contains auxiliary сам, dative му, then accusative га. The pronouns do not follow English order, and they cannot be placed freely after the participle.

Ако нађеш те шоље, купи ми их, молим те.

If you find those mugs, buy them for me, please.

The imperative купи asks for one completed purchase. Imperfective купуј is natural with repeated behavior or advice about a type of shopping: Купуј сезонско воће “Buy seasonal fruit.”

💡

With two object clitics, use the Serbian cluster order: auxiliary + dative + accusative, as in сам му га купила.

Купити is not платити

Купити profiles acquisition; платити profiles settling a price, charge, or obligation. One can pay without buying anything new, and one can buy now but pay later.

Телефон сам купио јуче, али ћу га плаћати на дванаест рата.

I bought the phone yesterday, but I’ll pay for it in twelve installments. (male speaker)

That contrast is developed on плаћати / платити.

Micro-dialogue

— Да ли сте већ купили карте за концерт? — Јесмо, купили смо их чим је почела продаја.

— Have you already bought the concert tickets? — Yes, we bought them as soon as sales opened. (formal/plural question)

The perfective question asks whether the purchase boundary was reached. Да ли сте куповали карте? would instead ask about involvement in buying, perhaps repeatedly or over a period.

Task 1: Choose aspect

Say that you normally buy coffee there, but today you bought tea.

Common Mistakes

Keeping -ова- in the present

❌ Сваке суботе куповам воће на пијаци.

Incorrect—the present stem changes -ова- to -уј-: купујем.

✅ Сваке суботе купујем воће на пијаци.

Every Saturday I buy fruit at the market.

Using perfective for an activity in progress

❌ Сада купим намирнице; позваћу те касније.

Incorrect—an ongoing activity requires imperfective купујем, not perfective купим.

✅ Сада купујем намирнице; позваћу те касније.

I’m buying groceries now; I’ll call you later.

Making the bought item genitive without a trigger

❌ Купили смо новог стола за трпезарију.

Incorrect—an inanimate masculine direct object stays accusative нови сто.

✅ Купили смо нови сто за трпезарију.

We bought a new table for the dining room.

Reversing the pronoun clitics

❌ Карте сам их му купила преко интернета.

Incorrect—the noun cannot be redundantly doubled here, and dative precedes accusative in the cluster.

✅ Карте сам му купила преко интернета.

I bought the tickets for him online. (female speaker)

Key Takeaways

Куповати is process/habit; купити is a bounded purchase.
Memorize куповати — купујем, not an invented present куповам.
The item is accusative; a beneficiary may be dative; source and price use their own prepositional frames.
Keep clitics ordered: сам му га купила, купи ми их.
