+# bs Glossary
+
+## Sources
+
+- PR #12283: https://github.com/anomalyco/opencode/pull/12283
+
+## Do Not Translate (Locale Additions)
+
+- `OpenCode` (preserve casing in prose; keep `opencode` only in commands, package names, paths, or code)
+- `OpenCode CLI`
+- `CLI`, `TUI`, `MCP`, `OAuth`
+- Commands, flags, file paths, and code literals (keep exactly as written)
+
+## Preferred Terms
+
+These are PR-backed locale naming preferences and may evolve.
+
+| English / Context                  | Preferred  | Notes                                             |
+| ---------------------------------- | ---------- | ------------------------------------------------- |
+| Bosnian language label (UI)        | `Bosanski` | PR #12283 tested switching language to `Bosanski` |
+| Repo locale slug (code/config)     | `bs`       | Preserve in code, config, paths, and examples     |
+| Browser locale detection (Bosnian) | `bs`       | PR #12283 added `bs` locale auto-detection        |
+
+## Guidance
+
+- Use natural Bosnian phrasing over literal translation
+- Preserve technical artifacts exactly: commands, flags, code, URLs, model IDs, and file paths
+- Keep repo locale references as `bs` in code/config, and use `Bosanski` for the user-facing language name when applicable
+
+## Avoid
+
+- Avoid changing repo locale references from `bs` to another slug in code snippets or config examples
+- Avoid translating product and protocol names that are fixed identifiers
