kupovati / kupiti (to buy) | Croatian Grammar

Kupiti ("to buy") is one of the first transactional verbs you need, and its aspect pair shows off a tidy piece of Croatian word-formation: the perfective kupiti versus the imperfective kupovati, whose present runs on the -uje- stem (kupujem). That -ovati → -uje- swap recurs across hundreds of verbs (putovati → putujem, darovati → darujem), so kupovati is a model worth knowing in full. The verb also opens the door to two case patterns English handles differently: the dative beneficiary ("buy someone something") and the partitive object ("buy some bread").

Aspect

Verb	Aspect	Present 1sg	Typical use
kupiti	perfective	kupim	one completed purchase
kupovati	imperfective	kupujem	shopping; repeated/habitual buying

The members split exactly along the line of "one purchase" vs "the activity of buying". Kupiti = I bought this specific thing (done). Kupovati = I shop / I buy (regularly) / I am out buying. So "I'm buying groceries right now" is kupujem, while "I bought milk" is kupio sam. This is a suffixal aspect pair (the imperfective is derived by the -ova- suffix) — see forming aspect pairs by suffixation.

💡

The present stem swap is the thing to drill: kupovati → kupujem, kupuješ, kupuje…, not *kupovam. Any -ovati verb does the same: drop -ova-, add -uje-. Compare putovati → putujem.

Present tense

Kupiti is a regular i-class verb; kupovati uses the -uje- present.

Person	kupiti (pf)	kupovati (impf)
ja	kupim	kupujem
ti	kupiš	kupuješ
on/ona/ono	kupi	kupuje
mi	kupimo	kupujemo
vi	kupite	kupujete
oni/one/ona	kupe	kupuju

As always, the perfective present kupim is not a "now" tense: Čim kupim kartu, javim ti ("As soon as I buy a ticket, I'll let you know"). For the act in progress you need kupujem.

Kupujem namirnice za vikend, treba li ti što?

I'm buying groceries for the weekend, do you need anything? — in progress, imperfective.

Ako kupim dvije, dobijem treću gratis.

If I buy two, I get the third free. — perfective present, conditional reading.

The l-participle

Both are regular -iti / -ovati verbs: masculine kupio (vocalised -l), kupovao.

Gender / number	kupiti	kupovati
masculine singular	kupio	kupovao
feminine singular	kupila	kupovala
neuter singular	kupilo	kupovalo
masculine plural	kupili	kupovali
feminine plural	kupile	kupovale
neuter plural	kupila	kupovala

Perfect tense (perfekt)

Clitic biti + l-participle. The everyday "I bought" is the perfective kupio sam; the imperfective kupovao sam marks a habit ("I used to buy / I was shopping").

Person	Masculine subject	Feminine subject
ja	kupio sam	kupila sam
ti	kupio si	kupila si
on / ona	kupio je	kupila je
mi	kupili smo	kupile smo
vi	kupili ste	kupile ste
oni / one	kupili su	kupile su

Kupila sam ti onu knjigu o kojoj si pričao.

I bought you that book you were talking about. — perfective, a single done purchase + dative 'ti'.

Prije smo kruh kupovali u susjednoj pekari.

We used to buy bread at the bakery next door. — imperfective, a past habit.

Future I (futur prvi)

Kupiti → kupit ću (drops -i); kupovati → kupovat ću.

Person	kupiti	kupovati
ja	kupit ću	kupovat ću
ti	kupit ćeš	kupovat ćeš
on/ona/ono	kupit će	kupovat će
mi	kupit ćemo	kupovat ćemo
vi	kupit ćete	kupovat ćete
oni/one/ona	kupit će	kupovat će

Kupit ću kruh kad se vraćam s posla.

I'll buy bread on my way back from work.

Imperative

The perfective kupi! ("buy [it]!") is the normal request for a specific purchase; the imperfective kupuj! leans toward "keep buying / do your shopping".

Person	kupiti (pf)	kupovati (impf)
ti	kupi	kupuj
mi	kupimo	kupujmo
vi	kupite	kupujte

Kupi mi, molim te, mlijeko i jaja.

Buy me some milk and eggs, please. — perfective + dative 'mi'.

Negative: Nemoj kupiti prvo što vidiš ("Don't buy the first thing you see").

Conditional I (kondicional prvi)

bih-clitics + l-participle — for polite requests and hypotheticals.

Person	kupiti (masc.)
ja	kupio bih
ti	kupio bi
on/ona/ono	kupio/kupila/kupilo bi
mi	kupili bismo
vi	kupili biste
oni/one/ona	kupili bi

Kupio bih taj auto da imam novca.

I'd buy that car if I had the money.

Other forms

Passive participle: kupljen, kupljena, kupljeno ("bought"). Note the p → plj jotation: an -iti verb with a labial stem (kup-) inserts the epenthetic -lj- in the passive participle — the same change as kupiti → kupljen, ljubiti → ljubljen. Used in novokupljen ("newly bought") and the passive: Stan je kupljen prošle godine. The imperfective kupovati gives kupovan.
Verbal adverb: imperfective kupujući ("[while] buying"). The perfective has no present adverb (perfectives never do).

Auto je kupljen iz druge ruke, ali je kao nov.

The car was bought second-hand, but it's like new. — passive participle 'kupljen'.

Key uses and government

1. The thing bought: accusative

The basic object of kupiti is the accusative — what you buy.

Kupili smo novi hladnjak za kuhinju.

We bought a new fridge for the kitchen. — accusative direct object.

2. The beneficiary: dative ("buy for someone")

To say who you buy for, Croatian uses the bare dative — no preposition, where English needs "for". This is the dative of the indirect object / beneficiary. The order is typically kupiti + dative person + accusative thing.

Kupio sam mami poklon za rođendan.

I bought my mum a birthday present. — dative beneficiary 'mami' (no preposition!).

Što da kupimo djeci za Božić?

What should we buy the kids for Christmas? — dative 'djeci'.

You may also say kupiti za + accusative ("buy for"), but for a person the plain dative is the natural choice. See dative: the indirect object.

3. The partitive object: genitive ("buy some")

For an unspecified quantity of a mass noun, the object can go into the partitive genitive instead of the accusative — "buy some bread / some milk". This is a flavour English carries with "some" but Croatian carries in the case ending.

Kupi kruha i mlijeka usput.

Buy some bread and milk on the way. — partitive genitive 'kruha', 'mlijeka'.

Kupi kruh.

Buy the/a bread. — accusative: the specific loaf, the whole thing.

The contrast kupi kruha (some bread) vs kupi kruh (the bread) is exactly the partitive-vs-whole distinction; see partitive genitive and quantity.

4. The opposite transaction: prodati / prodavati "to sell"

Kupiti (buy) pairs naturally with prodati / prodavati (sell), which takes the same accusative-thing + dative-person frame: Prodao sam mu auto ("I sold him the car"). See prodavati / prodati.

Kupili smo stan od njih, a oni su prodali da odu u inozemstvo.

We bought the flat from them, and they sold to move abroad.

Common Mistakes

❌ Kupovam mlijeko.

Wrong stem — '-ovati' verbs take the '-uje-' present: 'kupujem mlijeko'.

✅ Kupujem mlijeko.

I'm buying milk.

❌ Kupio sam za mamu poklon.

Unnatural — for a person beneficiary use the plain dative: 'mami poklon'.

✅ Kupio sam mami poklon.

I bought my mum a present.

❌ Stan je kupit prošle godine.

Wrong form — the passive participle is 'kupljen' (p → plj), not the bare infinitive stem.

✅ Stan je kupljen prošle godine.

The flat was bought last year.

❌ Sada kupim namirnice.

Aspect error — a perfective present can't mean 'right now'; the activity in progress is 'kupujem'.

✅ Sada kupujem namirnice.

I'm buying groceries now.

❌ Kupit ću ti onu knjigu.

This is actually correct! The pitfall to avoid is writing 'kupiti ću' — the infinitive must drop its -i before the clitic.

✅ Kupit ću ti onu knjigu.

I'll buy you that book.

Key Takeaways

kupiti (pf, kupim, kupio) = one purchase; kupovati (impf, kupujem, kupovao) = shopping/habit — note the -ovati → -uje- swap.
Object = accusative; beneficiary = bare dative ("buy someone something", no preposition).
Partitive object = genitive for "some": kupi kruha (some bread) vs kupi kruh (the bread).
Passive participle kupljen (p → plj jotation). Future drops -i: kupit ću (never kupiti ću).
Pairs with prodati / prodavati "to sell", which uses the same accusative + dative frame.
