# Translation Expertise

## Overview

This skill provides comprehensive translation expertise for English, Japanese, and Traditional Chinese. It covers translation methodologies, cultural considerations, and best practices for producing high-quality translations.

## Technical Documentation in This Workspace

Most translation here is engineering content. These rules take precedence over the general guidance below.

**Never translate**:

- Code blocks, inline code, identifiers, file paths, commands, CLI flags, URLs, frontmatter keys
- Markup and macros (HTML, JSX, Confluence storage format) — translate only the text nodes
- Severity prefixes and verdicts in review reports (⚠️ Critical, 💡 Suggestion, ❓ Question, 💅 Nit, 🎉 Praise, APPROVE / REQUEST CHANGES / BLOCK)

**Preserve structure 1:1**: same heading levels and order, lists, tables, links and anchors, so an `-en`/`-ja` (or `-zh`) pair diffs section by section.

**Japanese house style**:

- です/ます form for guidelines, specs and reports — not である調
- Keep framework and product names in English: React, Next.js, TanStack Query, Zustand, Zod, pnpm, PR
- Use the established katakana/Japanese for general concepts: コンポーネント, フック, 状態管理, デプロイ, レビュー
- Headings use `日本語 (English)` form, e.g. `コア原則 (Core Principles)`
- Full-width punctuation in Japanese prose; half-width inside code and identifiers

**Traditional Chinese house style**:

- Use 繁體中文 and Taiwan terminology by default (軟體, 網路, 資訊)
- Keep framework and product names in English
- Full-width punctuation in prose; half-width inside code and identifiers
- Use 成語 sparingly and only when it reads naturally

**Document pairs** (`*-en.md` / `*-ja.md` / `*-zh.md`): when one side changes, update the matching sections of the other in the same change, translating from the side that changed. Don't retranslate untouched sections.

**Output**: write the translation in place or to the requested file; list uncertain term choices briefly at the end, not inline.

**Web sources**: use `WebFetch` for simple pages; use the `agent-browser` / `browser-use` skills for interactive or JS-heavy pages. Don't use Playwright for text extraction; it is reserved for e2e tests.

## Translation Philosophy

### Core Principles

1. **Meaning over Literalness**: Convey the intended meaning rather than word-for-word translation
2. **Cultural Adaptation**: Adapt content for the target culture while preserving the original intent
3. **Natural Flow**: Translations should read naturally in the target language
4. **Contextual Accuracy**: Consider the broader context, not just individual words
5. **Tone Preservation**: Maintain the original tone (formal, casual, technical, emotional)

## Language-Specific References

For comprehensive information about each language, see the dedicated language reference files:

### [English](./english.md)

**Key Features**: SVO word order, explicit subjects and articles, direct communication style, active voice preference.

**Contains**: Structural features, formality indicators (informal/formal/academic), punctuation conventions, common idioms, phrasal verbs, modal verbs, translation strategies, regional variations (US/UK).

### [Japanese (日本語)](./japanese.md)

**Key Features**: SOV word order, context-dependent subject omission, three writing systems (hiragana, katakana, kanji), elaborate honorific systems (keigo).

**Contains**: All five politeness levels (plain, polite, respectful, humble, beautification) with detailed explanations, gendered speech patterns, particle usage, writing system guidelines, translation strategies, cultural concepts.

### [Chinese Traditional (繁體中文)](./chinese-traditional.md)

**Key Features**: SVO word order like English, no verb conjugation, measure words (classifiers) for counting, rich idiomatic expressions (成語).

**Contains**: Comprehensive measure word list, regional variations (Taiwan/Hong Kong/Macau), four-character idioms (成語), formality indicators, punctuation conventions, translation strategies, terminology differences.

## Translation Workflow

### Step 1: Initial Translation

**Process**:

1. Read the entire source text to understand context and intent
2. Identify key terminology and create a glossary
3. Translate section by section, maintaining context
4. Mark uncertain translations for review

**Considerations**:

- Understand the source culture and references
- Identify the target audience
- Determine appropriate formality level
- Note any ambiguities requiring clarification

### Step 2: Proofreading & Review

**Grammar and Syntax Check**:

- Verify sentence structure is natural in target language
- Check verb tenses and aspects
- Ensure particles (JA) or measure words (ZH) are correct
- Validate punctuation follows target language conventions (see language-specific files)

**Terminology Consistency**:

- Ensure consistent translation of key terms
- Verify technical terms are accurate
- Check proper nouns are handled correctly
- Confirm units and measurements are appropriate

**Cultural Adaptation**:

- Verify idioms are culturally appropriate (see [translation-challenges.md](./translation-challenges.md))
- Check for culturally sensitive content
- Ensure examples and analogies work in target culture
- Adapt humor if necessary

**Tone and Style**:

- Maintain consistent tone throughout
- Ensure formality level matches the source
- Verify the text flows naturally
- Check that emphasis and nuance are preserved

### Step 3: Refinement Translation

**Enhancement Process**:

1. Review feedback from proofreading
2. Resolve all marked uncertainties
3. Improve awkward phrasings
4. Polish for naturalness and readability
5. Final consistency check

**Quality Markers**:

- Reads naturally to native speakers
- Accurately conveys source meaning
- Maintains appropriate tone and style
- Consistent terminology throughout
- Free of grammatical errors

## Common Translation Challenges

> **Detailed Examples**: See [translation-challenges.md](./translation-challenges.md) for extensive examples with reasoning.

### Challenge 1: Idioms and Expressions

**Strategy**: Find equivalent expressions, not word-for-word translations.

**Examples**: "Break a leg" → 頑張って (JA) / 加油 (ZH); "Piece of cake" → 朝飯前 (JA) / 小菜一碟 (ZH)

### Challenge 2: Cultural References

**Strategy**: Adapt or explain references unfamiliar to target culture.

**Approaches**: Direct + explanation, cultural adaptation to equivalent concept, or generalization depending on context importance.

### Challenge 3: Wordplay and Puns

**Strategy**: Recreate the effect, not the exact wordplay.

**Approach**: Either explain the original wordplay with translator's note, or create new language-specific wordplay that achieves similar humor effect.

### Challenge 4: Formality Levels

**Strategy**: Match formality indicators across languages.

**Key**: English uses vocabulary and contractions; Japanese uses verb endings and honorifics; Chinese uses vocabulary and pronouns (你/您).

### Challenge 5: Ambiguity Resolution

**Strategy**: Use context clues, research, and informed judgment when source is ambiguous.

**Process**: Analyze context, research domain-specific meanings, apply logic, choose most likely interpretation, and document reasoning.

> **For Detailed Examples**: See [translation-challenges.md](./translation-challenges.md) for comprehensive examples with solutions.

## Punctuation Quick Reference

**Key Differences** (See language-specific files for complete details):

- Period: . (EN) → 。(JA/ZH)
- Comma: , (EN) → 、(JA) / 、or , (ZH)
- Quotation marks: "..." (EN) →「...」(JA/ZH) or "..." (ZH alternative)
- Book titles: "..." (EN) → 『...』(JA) /《...》(ZH)
- Ellipsis: ... (EN) → …… (JA/ZH - six dots)

**Important**: Use full-width punctuation for Japanese and Chinese text. Maintain consistency throughout the document.

> **Detailed Conventions**: See [english.md](./english.md), [japanese.md](./japanese.md), or [chinese-traditional.md](./chinese-traditional.md) for complete punctuation rules.

## Quick Reference

**When translating, remember**:

1. Read entire source text first for context
2. Create terminology glossary for consistency
3. Choose appropriate formality level early

8. Document difficult translation decisions

**Default choices when uncertain**:

- **Japanese**: Use です/ます polite form unless clear context suggests otherwise
- **Chinese**: Use 您 for formal contexts, 你 for casual; prefer Taiwan terminology unless specified
- **Punctuation**: Use「」for quotes in JA/ZH Taiwan style; use《》for book titles in Chinese
- **Idioms**: When direct equivalent unclear, prioritize conveying meaning over preserving metaphor
