Verb Tense Cheat Sheet | Croatian Grammar

The full Croatian verb system looks intimidating on paper — present, perfect, aorist, imperfect, two futures, pluperfect, imperative, conditional, participles, verbal adverbs. The good news, which this page exists to make visible at a glance, is that only a handful of those forms carry everyday conversation. Below is one ordinary verb — raditi ("to work / to do," an i-class imperfective) — shown in every tense and mood, with each form labelled for how often you actually need it. Learn the five "core" rows cold; recognise the rest.

The master table

Each row gives the form (1sg or the citation form), an English gloss, and a frequency tag: core (use it daily), recognition (understand it when you read/hear it), or formal/literary (mostly written or stylistically marked).

Form	raditi (model)	Meaning	Frequency
Infinitive	raditi	to work / to do	core
Present	radim	I work / I'm working	core
Perfect (perfekt)	radio sam	I worked / I have worked	core
Future I (futur I)	radit ću	I'll work	core
Imperative	radi! / radite!	work! (sg. / pl.)	core
Conditional I	radio bih	I would work	core
Future II (futur II)	budem radio	(when/if) I have worked	recognition
Pluperfect	bio sam radio	I had worked	recognition
Conditional II	bio bih radio	I would have worked	recognition
Aorist	radih / radi	I worked (narrative past)	literary
Imperfect (imperfekt)	rađah	I was working (narrative)	literary
L-participle	radio / radila / radilo	"worked" (builds compounds)	core (as a part)
Passive participle	rađen / rađena	(being / having been) done	recognition
Present verbal adverb	radeći	(while) working	recognition
Past verbal adverb	radivši	having worked	literary

💡

Five rows run almost all of spoken Croatian: present, perfect, future I, imperative, conditional I. If you can produce radim, radio sam, radit ću, radi!, radio bih for any verb, you can hold a full conversation. Everything else is for reading literature, sounding formal, or fine-tuning meaning — learn to recognise it before you try to produce it.

The five core forms

These are the ones to drill until they are automatic. Notice how four of the five are built from just two ingredients: the present stem (for present and imperative) and the l-participle radio (for perfect and conditional), plus the infinitive for the future.

Radim u bolnici već deset godina.

I've been working at the hospital for ten years. — present 'radim'.

Jučer sam radio do ponoći.

Yesterday I worked until midnight. — perfect 'radio sam'.

Sutra ću raditi od kuće.

Tomorrow I'll work from home. — future I 'radit ću', here clause-initial so 'ću raditi'.

Radi tiše, dijete spava!

Work more quietly, the child is sleeping! — imperative 'radi'.

Radio bih i vikendom da bolje plaćaju.

I'd work weekends too if they paid better. — conditional I 'radio bih'.

The recognition forms

You will meet these in news, contracts, and careful speech, but you rarely need to produce them as a learner. Recognising them is enough.

Future II sets up a future condition or time clause — it pairs with kad / ako / čim:

Kad budem radio u Zagrebu, vidjet ćemo se češće.

When I'm working in Zagreb, we'll see each other more often. — future II 'budem radio'.

Pluperfect marks a past-before-the-past; everyday speech usually just uses the plain perfect instead:

Bio sam već radio na sličnom projektu, pa mi je bilo lako.

I had already worked on a similar project, so it was easy for me. — pluperfect 'bio sam radio'.

Conditional II is the "would have" of unrealised past situations:

Bio bih radio, ali sam bio bolestan.

I would have worked, but I was ill. — conditional II 'bio bih radio'.

Passive participle turns the verb into something done-to a subject, and feeds the periphrastic passive:

Posao je dobro odrađen.

The job is well done. — passive participle (from the prefixed 'odraditi') in a passive construction.

Present verbal adverb compresses a "while …-ing" clause into a single word:

Radeći cijeli dan, zaboravio je jesti.

Working all day, he forgot to eat. — present verbal adverb 'radeći'.

The literary forms

The aorist (radih, radi, radi, radismo, radiste, radiše) and imperfect (rađah…) are the old narrative past tenses. In modern spoken Croatian they are largely replaced by the perfect — you meet them mainly in literature, fairy tales, the Bible, and a few fixed expressions. The most living aorist forms are bih (now repurposed as the conditional auxiliary) and reče / dođe in storytelling.

Tada reče kralj svojoj kćeri…

Then the king said to his daughter… — aorist 'reče', the storytelling past you'll see in tales.

💡

Don't invest production effort in the aorist, imperfect, or past verbal adverb early on. They are literary. Aim only to recognise them — and to know that when a native speaker tells you a story in conversation, they will almost always use the everyday perfect, not these.

How the forms connect

Two building blocks generate most of the compound system:

The l-participle radio / radila / radilo / radili combines with an auxiliary to make the perfect (radio sam), pluperfect (bio sam radio), future II (budem radio), and conditional (radio bih, bio bih radio).
The infinitive raditi combines with the htjeti clitic to make future I (radit ću).

Master the l-participle and the infinitive of a verb and almost every compound tense falls out mechanically.

Common Mistakes

❌ Ja sam radim svaki dan.

Incorrect — present needs no auxiliary; 'sam' belongs to the perfect, not the present.

✅ Radim svaki dan.

I work every day.

❌ Sutra radim u uredu (meaning 'I will work').

Acceptable colloquially for a scheduled plan, but the explicit future is clearer here.

✅ Sutra ću raditi u uredu.

Tomorrow I'll work in the office. — explicit future I.

❌ Radih cijeli dan (in casual conversation).

Unidiomatic in everyday speech — the aorist is literary; use the perfect.

✅ Radio sam cijeli dan.

I worked all day.

❌ Bih radio sutra.

Incorrect — 'bih' is the conditional ('would'), not a future; for 'I'll work' use 'radit ću'.

✅ Radit ću sutra.

I'll work tomorrow.

Key Takeaways

The whole verb system reduces to five core forms: present radim, perfect radio sam, future I radit ću, imperative radi!, conditional I radio bih.
Recognition forms (future II, pluperfect, conditional II, passive participle, present verbal adverb) you should understand but rarely need to produce.
Literary forms (aorist, imperfect, past verbal adverb) are for reading; everyday speech replaces them with the perfect.
Most compound tenses are built from the l-participle (radio) or the infinitive (raditi) plus an auxiliary — learn those two and the rest follows.
