Spelling Conventions: Caps, Hyphens, Joined/Split | Croatian Grammar

Beyond knowing which letters to type, fluent writing in Croatian rests on a handful of orthographic conventions that English speakers consistently get wrong: how much of a multiword name to capitalize, when a negative particle fuses onto its word and when it floats free, and how the language hyphenates a small class of "half-and-half" compounds. None of these are spelling in the sound-to-letter sense; they are conventions about word boundaries and capitals (pravopisne konvencije). This page collects the three that matter most for a B1 writer.

Capitalization: only the first word of a multiword name

Croatian capitalizes genuine proper names, but in a multiword name or title it capitalizes only the first word — every other word stays lowercase unless it is itself a proper noun. English capitalizes nearly every significant word in a name ("the European Union", "the United Nations"); Croatian does not. This is the single most over-capitalized area for English speakers.

English	Croatian	Note
the European Union	Europska unija	only Europska is capital
the United Nations	Ujedinjeni narodi	only Ujedinjeni
the Ministry of Foreign Affairs	Ministarstvo vanjskih poslova	only Ministarstvo
the University of Zagreb	Sveučilište u Zagrebu	Zagrebu stays capital (it is a place name)

Hrvatska je članica Europske unije od 2013. godine.

Croatia has been a member of the European Union since 2013.

Ujedinjeni narodi raspravljaju o klimatskoj krizi.

The United Nations is discussing the climate crisis.

The only word inside such a name that keeps its own capital is an embedded proper noun — a city, a country, a personal name. So in Sveučilište u Zagrebu, the word Zagrebu is capitalized because Zagreb is a place; Sveučilište is capitalized only because it leads the name.

Lowercase: days, months, languages, nationalities-as-adjectives

Categories that English treats as inherently capital-worthy are lowercase in Croatian, because they are not the unique name of one specific thing. This is covered in full on the capitalization page; the short version:

Vidimo se u ponedjeljak, negdje sredinom svibnja.

See you on Monday, sometime in the middle of May.

Učim hrvatski, a sestra mi uči talijanski.

I'm learning Croatian, and my sister is learning Italian.

Days (ponedjeljak), months (svibanj), languages and nationality-adjectives (hrvatski, talijanski) all stay lowercase.

The polite Vi capitalized in letters

When you address someone formally with the polite second person, it is a courtesy to capitalize Vi, Vas, Vam, Vaš in letters, emails, and formal correspondence (formal). The same forms in lowercase (vi, vas) are the ordinary plural "you" addressing several people.

Poštovani, zahvaljujem Vam na brzom odgovoru i šaljem Vam tražene dokumente.

Dear Sir/Madam, thank You for the quick reply and I am sending You the requested documents.

💡

One test resolves most capitalization questions: ask „is this the unique name of one specific thing?" A multiword name has exactly one first word that opens it — capitalize that, then stop unless you hit a name inside.

Joined vs split: where the negative particle goes

Croatian draws a sharp, rule-governed line — sastavljeno (joined) vs rastavljeno (split) writing — over the negative particle ne. The logic is grammatical category, and once you know it you never have to guess.

ne is SEPARATE from a verb

With a finite verb, ne is written as a separate word before it. It is its own stressed unit.

Ne znam gdje su mi ključevi.

I don't know where my keys are.

Danas ne radim, pa možemo na kavu.

I'm not working today, so we can go for a coffee.

ne is JOINED in nouns and adjectives

When ne negates a noun or an adjective, it fuses onto the front of the word, written as one word.

Joined (one word)	Meaning	Category
neznanje	ignorance (lit. non-knowing)	noun
nesreća	misfortune / accident	noun
nemoguć	impossible	adjective
nezadovoljan	dissatisfied	adjective

Njegovo neznanje o toj temi bilo je očito.

His ignorance of that topic was obvious.

To je gotovo nemoguć zadatak za jednu osobu.

That's a nearly impossible task for one person.

The contrast is the whole point: ne znam (split, "I don't know") versus neznanje (joined, "ignorance"). For the full set of noun/adjective negations and their nuances, see negation of nouns and adjectives.

Fused negatives: nemam, neću, nije

Three high-frequency verbs fuse with ne as a fixed, joined form — these are spelling exceptions you simply learn. They are the negatives of imati (have), htjeti (want / future auxiliary), and biti (be).

Positive	Negative (joined)	Meaning
imam	nemam	I don't have
hoću / ću	neću	I won't / I don't want
je	nije	he/she/it isn't

Nemam pojma, ali nije važno.

I have no idea, but it doesn't matter.

Neću ti više ništa reći.

I won't tell you anything more.

💡

The three fused negatives nemam, neću, nije are the only common verbs where ne joins. Every other verb keeps it split: ne radim, ne dolazim, ne mogu. Memorize the three exceptions and the rest is mechanical.

ni s kim: split around a preposition

The negative pronoun nitko (nobody) and its relatives normally write ni- joined: nitko, ništa, nikad. But when a preposition comes between, the ni splits off and the preposition wedges in the middle — ni s kim ("with nobody"), ni o čemu ("about nothing"), ni za što ("for nothing"). This "split around the preposition" is a hallmark of careful Croatian and a frequent error.

Nisam o tome ni s kim razgovarala.

I didn't talk about it with anybody.

Ne brini se ni za što, sve je pod kontrolom.

Don't worry about anything, everything's under control.

na primjer: written as two words

The phrase meaning "for example" is written separately — na primjer — not as one word, even though it functions as a single connector. (The abbreviation is npr.)

Voli toplije krajeve, na primjer Dalmaciju ili Istru.

She likes warmer regions, for example Dalmatia or Istria.

Hyphenation of half-compounds

Croatian uses a hyphen for a narrow but useful class: coordinate compounds where the two parts are equal-ranked and could be joined by "and" — typically two colours, two directions, or paired nationalities. The hyphen signals "X and Y", and each part keeps its own ending where relevant.

Hyphenated	Meaning	Why a hyphen
crno-bijeli	black-and-white	black and white, equal parts
hrvatsko-engleski	Croatian-English (e.g. dictionary)	both languages, paired
društveno-politički	socio-political	two coordinate domains

Gledali smo stari crno-bijeli film s djedom.

We watched an old black-and-white film with grandpa.

Kupila sam hrvatsko-engleski rječnik za fakultet.

I bought a Croatian-English dictionary for university.

Contrast this with a subordinate compound, where the first part modifies the second (it is not "X and Y" but "a kind of Y"): there the words are written joined, no hyphen — tamnoplav "dark blue" (a shade of blue, not "dark and blue"), svijetlozelen "light green". The test: if you can paraphrase with "and", hyphenate; if the first part just grades or modifies the second, join.

Common Mistakes

❌ Hrvatska je članica Europske Unije.

Incorrect — in a multiword name only the first word is capital.

✅ Hrvatska je članica Europske unije.

Croatia is a member of the European Union.

❌ Njegovo ne znanje bilo je očito.

Incorrect — with a noun, 'ne' joins: neznanje.

✅ Njegovo neznanje bilo je očito.

His ignorance was obvious.

❌ Ja neznam gdje su ključevi.

Incorrect — with a verb, 'ne' is a separate word.

✅ Ja ne znam gdje su ključevi.

I don't know where the keys are.

❌ Nisam o tome niskim razgovarala.

Incorrect — a preposition splits the negative: ni s kim.

✅ Nisam o tome ni s kim razgovarala.

I didn't talk about it with anybody.

❌ Gledali smo crnobijeli film.

Incorrect — a coordinate 'black-and-white' compound takes a hyphen.

✅ Gledali smo crno-bijeli film.

We watched a black-and-white film.

Key Takeaways

In a multiword name, capitalize only the first word (Europska unija, Ujedinjeni narodi) — plus any embedded place or personal name (Sveučilište u Zagrebu).
Days, months, languages, and nationality-adjectives stay lowercase; the polite Vi/Vas is capitalized in formal letters.
ne is split from a verb (ne znam) but joined to a noun/adjective (neznanje, nemoguć); the three fused verb negatives are nemam, neću, nije.
A preposition splits the negative pronoun: ni s kim, ni o čemu. And na primjer is two words.
Hyphenate coordinate half-compounds you could paraphrase with "and" (crno-bijeli, hrvatsko-engleski); join modifier compounds (tamnoplav).
