+## 16. Code Comments Language
+
+**All code comments must be in English**, regardless of the user's language. This ensures:
+
+- Consistent codebase for international collaboration
+- Better compatibility with AI tools
+- Easier code review and maintenance
+
+```typescript
+// ✅ GOOD: English comments
+function calculateTotal(items: Item[]): number {
+  // Sum up all item prices
+  return items.reduce((sum, item) => sum + item.price, 0);
+}
+
+// ❌ BAD: Non-English comments
+function calculateTotal(items: Item[]): number {
+  // Additionner tous les prix des articles
+  return items.reduce((sum, item) => sum + item.price, 0);
+}
+```
+
+This rule applies to:
+
+- Inline comments
+- Function/class documentation (JSDoc)
+- Block comments explaining logic
+- TODO/FIXME notes
+- Commit messages (covered in Git Workflow section)
+
+**Exception**: User-facing strings in UI components may be in any language (they will be localized later).
