Declining Acronyms and Initialisms
In Croatian, capitalized acronyms and initialisms—such as UN, NATO, or SAD (USA)—are almost always treated as regular masculine nouns. This applies regardless of the gender of the underlying words they stand for.
To decline them, you simply attach standard masculine case endings to the capitalized letters using a hyphen. The nominative case (used for the subject) takes no ending.
| Case | Ending | Example |
|---|---|---|
| Nominative | (none) | SAD |
| Genitive | -a | SAD-a |
| Dative/Locative | -u | SAD-u |
| Instrumental | -om / -em | SAD-om |
The genitive ending -a is extremely common in geopolitical and diplomatic contexts. It is used to express possession (such as "of the UN" or "of NATO") and follows prepositions like između (between) and iza (behind).
| The ambassador of the USA arrived at the NATO headquarters. | Veleposlanik SAD-a stigao je u sjedište NATO-a. |
| The agreement between NATO and the USA is important. | Sporazum između NATO-a i SAD-a je važan. |
| The UN council adopted the resolution. | Vijeće UN-a prihvatilo je rezoluciju. |
This hyphenation rule applies consistently to economic acronyms as well, such as MMF (IMF) and BDP (GDP). If you need to express "with the IMF," you use the preposition s followed by the acronym with the instrumental ending -om.
| The IMF director expects GDP growth. | Direktor MMF-a očekuje rast BDP-a. |
| He read the report before he signed the agreement with the IMF. | Pročitao je izvještaj prije nego što je potpisao sporazum s MMF-om. |
When multiple acronyms appear in the same sentence, each simply takes the hyphenated ending appropriate for its grammatical role. An acronym acting as the subject remains in the bare nominative, while others take endings based on their relationship to the nouns or prepositions around them.
| The USA is a member of NATO and the IMF. | SAD je član NATO-a i MMF-a. |
