+# br Glossary
+
+## Sources
+
+- PR #10086: https://github.com/anomalyco/opencode/pull/10086
+
+## 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`
+- Locale code `br` in repo config, code, and paths (repo alias for Brazilian Portuguese)
+
+## Preferred Terms
+
+These are PR-backed locale naming preferences and may evolve.
+
+| English / Context                        | Preferred                      | Notes                                                         |
+| ---------------------------------------- | ------------------------------ | ------------------------------------------------------------- |
+| Brazilian Portuguese (prose locale name) | `pt-BR`                        | Use standard locale naming in prose when helpful              |
+| Repo locale slug (code/config)           | `br`                           | PR #10086 uses `br` for consistency/simplicity                |
+| Browser locale detection                 | `pt`, `pt-br`, `pt-BR` -> `br` | Preserve this mapping in docs/examples about locale detection |
+
+## Guidance
+
+- This file covers Brazilian Portuguese (`pt-BR`), but the repo locale code is `br`
+- Use natural Brazilian Portuguese phrasing over literal translation
+- Preserve technical artifacts exactly: commands, flags, code, URLs, model IDs, and file paths
+- Keep repo locale identifiers as implemented in code/config (`br`) even when prose mentions `pt-BR`
+
+## Avoid
+
+- Avoid changing repo locale code references from `br` to `pt-br` in code snippets, paths, or config examples
+- Avoid mixing Portuguese variants when a Brazilian Portuguese form is established
