## Translating into this locale

Apply [[locale-sr-001]] with the conventions of Bosnia and Herzegovina (Serbian).

- **Variant:** Serbian in Bosnia (especially Republika Srpska) is usually ijekavian: `лијепо`, `млијеко`, `ријеч`. Use ijekavian forms unless the audience requires ekavian.
- **Script:** Cyrillic and Latin are both used; Republika Srpska officials use Cyrillic.
- **Formats:** convertible mark (`КМ`, `BAM`); dates `17.10.2026.`; decimal comma.
- **Context:** Bosnian, Croatian, and Serbian are all official; do not replace Serbian forms with Bosnian or Croatian forms in Serbian-language content.

## Common pitfalls

- Using ekavian forms for a Republika Srpska audience.
- Mixing Bosnian or Croatian terms into Serbian text.
- The general pitfalls in [[locale-sr-001]] also apply.
