### Translations

Supervertaler Workbench has an early-stage i18n system (v1.10.208+). The menu bar, Settings tabs, and key group titles are translatable; dialog bodies and error messages remain in English for now.

Translation files are **XLIFF 1.2**, so translators can open them in **Trados, memoQ, Phrase, OmegaT, or Supervertaler Workbench itself** – any CAT tool that handles XLIFF (all of them do).

| Locale  | Language                          | Status                |

| ------- | --------------------------------- | --------------------- |

| `en`    | English                           | source language       |

| `zh_CN` | 简体中文 — Simplified Chinese     | scaffold (sanity-translated samples) |

| `zh_TW` | 繁體中文 — Traditional Chinese    | scaffold (untranslated) |

| `pl`    | Polski — Polish                   | scaffold (untranslated) |

Want to contribute a translation? See [`translations/TRANSLATING.md`](translations/TRANSLATING.md). Workflow: open the locale's `.xlf` in your normal CAT tool, translate, PR back. No build step on your end.
