The Reflexive Possessive "Svoj"
In Croatian, svoj is a special possessive determiner used when the subject of the sentence is also the owner of the object. It translates broadly to "one's own."
| one's own | svoj |
Like all possessives, it declines to match the gender, number, and case of the noun it modifies. You can use it whenever the "doer" of the action is acting upon their own belongings.
| I am looking for my passport. | Tražim svoju putovnicu. |
| She cannot find her passport in the hotel. | Ona ne može naći svoju putovnicu u hotelu. |
| You must change your bad habits. | Morate promijeniti svoje loše navike. |
The Crucial Contrast: "Svoj" vs. Regular Possessives
While using svoj is somewhat optional for "I" or "you" (since "I am looking for my passport" isn't highly ambiguous), it is strictly required in the third person (he, she, they).
If you use a regular third-person possessive like njegov (his) or njen (her), Croatian speakers will naturally assume the object belongs to someone else. Notice how svoj completely changes the meaning of the sentence:
| The colleague is doing his own task. | Kolega radi svoj zadatak. |
| The colleague is doing his [another person's] task. | Kolega radi njegov zadatak. |
Because svoj always reflects back to the subject, its exact English translation adapts depending on who the subject is (my own, your own, his own, their own, etc.).
| They will describe their experience. | Opisat će svoje iskustvo. |
| You must take care of your health. | Moraš paziti na svoje zdravlje. |
