This guide adapts rules and examples from Microsoft’s Localization Style Guide for Croatian (originally written for software/UI localization). The underlying linguistic rules apply universally — to legal contracts, medical documents, marketing copy, and any Croatian translation work. Restructured and reformatted as a general Croatian translator reference by ChatsControl.

Croatian Translation Style Guide — Voice, Word Choice & Common Pitfalls (Legal, Medical, Marketing, IT)¶

TL;DR¶

• Croatian translation prefers everyday vocabulary over bureaucratic alternatives — Provjerite je li (not Pobrinite se da je), Nema podataka (not Podaci nedostaju), sadrži/ima (not uključuje sljedeće); applies to marketing, software UI, patient instructions, and consumer legal documents.
• Use standard Croatian, not local dialects — avoid kajkavski/čakavski regional vocabulary that won’t be understood by all Croatian audiences across the country and diaspora.
• Follow the 2013 Hrvatski pravopis from the Institut za hrvatski jezik i jezikoslovlje (pravopis.hr) as the normative orthographic reference — distinguishes Croatian from Serbian and Bosnian conventions in spelling and word choice.
• Address users with the formal vi (capitalized Vi when needed in correspondence) in standard product voice — never use the impersonal third person or the informal ti for consumer-facing translation.
• Reference Šonje Rječnik hrvatskoga jezika, Anić Rječnik hrvatskoga jezika, Hrvatski enciklopedijski rječnik, Klaić Rječnik stranih riječi, Hrvatska gramatika (Barić et al.), and hjp.znanje.hr as authoritative Croatian dictionaries and grammar references.

Register and tone for modern Croatian translation¶

Register is the level of formality, warmth, and conversational ease the target text projects. Modern Croatian readers across consumer-facing spheres expect a clear, friendly, concise register that resembles everyday conversation rather than the bureaucratic register traditional in commercial and administrative content.

Three principles define the target register:

• Warm and relaxed. Natural, less formal, more grounded in honest conversation.
• Crisp and clear. Written for scanning first, reading second.
• Ready to help. Anticipates user needs.

Use standard Croatian (književni jezik) — avoid words from local dialects (kajkavski, čakavski) that may not be understood by all Croatian audiences.

Why this matters: Bureaucratic Croatian damages outcomes across spheres. In marketing translation to Croatian consumers, the audience expects modern accessible voice rather than administrative officialdom. In medical patient materials it reduces comprehension. In software UI it creates friction. In government translation modern Croatian public-sector communications increasingly favor accessible language. Only sworn legal translation and traditional literary contexts retain the older formal register.

Flexibility: when to translate literally vs. when to rewrite¶

Modify or rewrite translated strings so they sound natural to Croatian customers. Try to understand the whole intention, then rewrite as if you’re writing the content yourself.

Word choice: terminology and everyday vocabulary¶

Approved terminology¶

Use approved terminology from Microsoft language resources where applicable.

Short word forms and everyday words¶

Croatian doesn’t shorten words as freely as English. “App” and “application” both translate as “aplikacija” — no short form. However, some expressions can be shortened by omitting a word.

Other forms: “računalo” (instead of “osobno računalo”) for PC in informal context.

Word-for-word translation¶

To achieve fluent Croatian, avoid word-for-word translation. Literal translation produces stiff, unnatural text. Split sentences if it helps simplify; omit descriptors to make text snappier.

Words and phrases to avoid¶

Modern Croatian voice avoids unnecessarily formal tone.

Why this matters: Bureaucratic Croatian vocabulary signals institutional distance. In marketing translation “Pobrinite se da je” reads as administrative; “Provjerite je li” reads as conversation. In medical patient instructions “Izvršiti promjene” reads as clinical; “Unijeti izmjene” reads as direct advice. In software UI these substitutions immediately improve register.

Sample translations: applying voice principles in context¶

Focusing on the user action¶

Explanatory text and providing support¶

Promoting a feature¶

Providing how-to guidelines¶

Inclusive language¶

All communications should be inclusive and diverse.

General guidelines:

• Use plain language.
• Be mindful when referring to various parts of the world.
• Represent diverse perspectives.
• Don’t generalize or stereotype people.
• Don’t use profane, derogatory, or culturally appropriative slang.
• Don’t use terms with unconscious racial bias.

Avoid gender bias¶

Croatian has grammatical gender. Use gender-neutral alternatives:

• Collective nouns where possible (osoblje, korisnici).
• Plural forms (sudionici, polaznici).
• Rewrite to second person (vi).
• Refer to a person’s role.

When writing about a real person, use the pronouns the person prefers.

Accessibility¶

Focus on people, not disabilities. Use generic verbs that apply to all input methods. Keep paragraphs short, one verb per sentence.

Language-specific standards¶

Abbreviations¶

Common Croatian abbreviations follow standard conventions (npr. — for example, itd. — etc., tj. — that is). Most computing acronyms remain in English (PC, USB, HTML).

Acronyms¶

Computing acronyms typically remain in English. Croatian abbreviations follow the Hrvatski pravopis conventions.

Adjectives¶

Croatian adjectives agree with their noun in gender, number, and case. Adjectives precede the noun.

Capitalization¶

Croatian capitalization follows European conventions — proper nouns and first word of sentence are capitalized. Don’t capitalize common nouns or feature labels mid-sentence.

Compounds¶

Croatian compounds may be formed with hyphens or as single words. Consult Hrvatski pravopis and dictionaries.

Conjunctions¶

Use natural conjunctions — i (and), ili (or), ali (but). Avoid overly formal alternatives.

Gender¶

Croatian nouns have masculine, feminine, and neuter genders. Adjectives, verbs, and pronouns agree with grammatical gender.

For generic user references, masculine forms are conventional. Prefer direct address (vi) to avoid gender on unknown audience.

Localizing colloquialism, idioms, and metaphors¶

Translate intended meaning, not literal colloquialism.

Modifiers¶

Croatian modifiers follow noun-adjective standards. Adjectives precede noun in attribute position.

Nouns¶

Use approved Croatian nouns from termbases. Croatian distinguishes seven cases (nominative, genitive, dative, accusative, vocative, locative, instrumental) — careful inflection required.

Prepositions¶

Croatian prepositions govern specific cases. Be careful with case-marking after prepositions.

Pronouns¶

Address users with vi (formal plural). Capitalize Vi only in personal correspondence. Possessive: vaš/vaša/vaše/vaši.

Punctuation¶

Croatian punctuation generally follows European conventions:

• Period (.) — end of sentences.
• Comma (,) — Croatian uses comma extensively.
• Question mark (?) — at end.
• Quotation marks — Croatian uses „”” (lower-upper for primary quotes) or « » (guillemets).
• Dashes — en dash for ranges, em dash for emphasis.

Sentence fragments¶

UI strings often use sentence fragments. Don’t artificially expand if source is terse.

Symbols and nonbreaking spaces¶

Use nonbreaking spaces between numerical values and units.

Verbs¶

Croatian verb aspects (perfective/imperfective) and tenses:

• Present for general statements.
• Past (perfect tense) for completed actions.
• Future for future events.
• Imperative for instructions.

Use formal imperative (-ite) for user-facing instructions matching the vi address.

Localization considerations¶

Accessibility¶

Generic verbs that work with all input methods. Short paragraphs, one verb per sentence.

Applications, products, and features¶

Microsoft product names are trademarked and not translated.

Copilot predefined prompts¶

Copilot prompts are functional — translations must be accurate, consistent, concise, natural. Be clear and specific; keep it conversational; be polite and professional; use quotation marks; pay attention to entity tokens; place ghost text at end of sentence; be consistent.

Trademarks¶

Trademarked names should not be localized.

Software considerations¶

Standard software localization conventions apply. Error messages should be natural and empathetic. Key names typically remain in English.

FAQ¶

How do I address users in Croatian translation?¶

Use vi (formal second-person plural). Capitalize Vi only in formal personal correspondence; in product UI and general translation, lowercase vi is standard. Avoid ti (informal singular) in consumer-facing product translation, marketing, and patient materials — it’s too familiar. Use direct verb forms (Provjerite, Kliknite, Unesite) in instructions to maintain the modern voice without overusing “vi” itself.

Which Croatian vocabulary should I avoid in modern translation?¶

Bureaucratic phrases: Pobrinite se da je (use Provjerite je li), Podaci nedostaju (use Nema podataka), uključuje sljedeće (use sadrži/ima), Izvršiti promjene (use Unijeti izmjene/izmijeniti), Imati mogućnosti / biti u stanju (use moći), Dati do znanja (use Upozoriti, pokazati, reći), Ukazati pomoć (use Pomoći), S ciljem… / u svrhu… (use Radi…). These formal forms have everyday equivalents that read as native modern Croatian.

What’s the difference between Croatian and Serbian/Bosnian orthography?¶

Croatian follows the 2013 Hrvatski pravopis (Institut za hrvatski jezik i jezikoslovlje) which prescribes specific spellings distinct from Serbian (Latin) and Bosnian conventions. Key differences: Croatian je/ije (vrijeme), Serbian e (vreme); Croatian uses ć/č distinction strictly; vocabulary differences (Croatian zrak vs. Serbian vazduh for “air”). Use the Razlikovni rječnik srpskog i hrvatskog jezika (Brodnjak) for distinguishing Croatian from Serbian vocabulary.

Which authoritative references should I use for Croatian translation?¶

Normative: pravopis.hr (Institut za hrvatski jezik i jezikoslovlje orthographic rules), Hrvatski pravopis (2013), Croatian online encyclopedia (enciklopedija.hr), Croatian online terminology portal (nazivlje.hr), Šonje Rječnik hrvatskoga jezika (Leksikografski zavod Miroslav Krleža), Anić Rječnik hrvatskoga jezika, Klaić Rječnik stranih riječi (foreign words), and Hrvatska gramatika (Barić et al., Školska knjiga). Supplement with hjp.znanje.hr (online dictionary), Croatian National Corpus, and Brodnjak Razlikovni rječnik (Croatian-Serbian distinction).

How should I handle ‘app’ vs. ‘application’ in Croatian?¶

Both translate as “aplikacija” — Croatian doesn’t have a short form for “app” that works the way it does in English. Other short forms work better: “računalo” can replace “osobno računalo” (PC) in informal context; “tablet” replaces “tablet računalo” or “tablet PC” in informal explanations; “video” replaces “videozapis” when no inflection is needed; “disk” replaces “pogon” when drive actually refers to a disk.

Should I avoid Serbian-influenced vocabulary in Croatian translation?¶

Yes — modern Croatian translation conventions distinguish standard Croatian from Serbian (Latin script) vocabulary. Use Croatian forms: zrak (not vazduh), tisuću (not hiljadu), siječanj/veljača (not januar/februar), nogomet (not fudbal), tjedan (not nedjelja in “week” sense). Consult Brodnjak Razlikovni rječnik when uncertain. This is especially important in marketing translation and legal documents distributed in Croatia.

How do I handle Croatian case inflection of borrowed English terms?¶

English borrowings should be inflected per Croatian grammar where they have entered general use: PC → PC-ja, PC-ju (with hyphen before case ending); email → e-pošta (full Croatian form); Windows → Windowsa, Windowsu (genitive, dative). Product names that are trademarks should generally not be modified — use prepositional constructions instead (s aplikacijom Windows, not “Windowsova aplikacija”).
