Language Standards Multi-Language Tone & Grammar

Overview

Use this skill as the multilingual language-governance layer for the repository. It keeps English, French, and Kiswahili content professional, culturally appropriate, and internally consistent across translated or multi-language outputs.

Use When

• Use when content is being created or reviewed across more than one supported language.
• Use when translation quality, tone consistency, or cultural fit matter.
• Use as a language overlay on top of another content skill.

Do Not Use When

• Do not use as a substitute for core strategy, structure, or factual accuracy.
• Do not force identical phrasing across languages when natural usage differs.
• Do not let localisation drift into meaning changes.

Required Inputs

• Source text or content brief
• Target language or set of languages
• Audience, country, and cultural context
• Any fixed terminology, brand language, or compliance phrasing

Workflow

1. Identify the target language, audience, and purpose of the content.
2. Apply the relevant language-specific standards and tone rules.
3. Preserve meaning while adapting phrasing for natural local usage.
4. Keep terminology and brand cues consistent across languages.
5. Reconcile multilingual outputs with the source content and site structure.
6. Flag terms or nuances that require human confirmation.

Quality Bar

• The language feels natural to its target audience.
• Meaning stays consistent across languages.
• Tone matches the brand and region.
• Terminology is controlled and repeatable.

Anti-Patterns

• Word-for-word translation that sounds unnatural.
• Letting one language version drift strategically from the others.
• Mixing registers or regional variants unintentionally.
• Ignoring culture-specific connotations in business language.

Outputs

• Language-standard-compliant content or edits across the supported languages
• Terminology and tone corrections
• Any localisation questions requiring follow-up

All website copy, headings, calls to action, descriptions, and microcopy must follow this style guide for their respective language. This is a cross-cutting standard applied throughout every content-writing step.

Core Principles (All Languages)

1. Clear and direct. Sentences are straightforward, grammatically careful, logically structured.
2. Formal and respectful. Politeness is essential. Communication shows courtesy and humility.
3. No excessive marketing language. Avoid drama, exaggeration, slang.
4. Professionally indirect. Soften directives with courteous phrasing.
5. Measured confidence. Confident without arrogance.
6. Culturally authentic. Respect regional norms, preferences, sensitivities.

ENGLISH (en) British English, East African Professional Standard

Load east-african-english for the English spelling, dates, country register, courtesy, vocabulary, and CTA rules. This multilingual skill retains only cross-language decisions and the French and Kiswahili standards so the two entrypoints do not drift.

Assertive Language (All Languages)

Hedging language communicates uncertainty. If you're not sure you're any good, how can prospects be? Replace weak phrasing with confident, assertive alternatives:

This applies across all three languages. In French: "N'hesitez pas a nous contacter" is acceptable (culturally standard), but avoid excessive hedging like "Il serait eventuellement possible de...". In Kiswahili: use direct invitations ("Wasiliana nasi" not "Labda unaweza kuwasiliana nasi").

Cross-language anti-slop control

Apply anti-ai-slop while drafting and ai-slop-audit before release. Translate intent and evidence rather than banned-word lists mechanically; language-specific filler and condescension still require concrete correction.

FRENCH (fr) Francophone African Professional Standard

Core Characteristics

1. Formal francophone African French not Quebecois, not Belgian variants.
2. Respectful and courteous professionalism with warmth.
3. Standard French grammar and conventions.
4. Vous (formal) throughout all professional communication never "tu".
5. Culturally appropriate for Cote d'Ivoire, Cameroon, Senegal, DRC, Gabon.

French Spelling and Grammar

Use standard French orthography:

• Accent marks required: e, e, e, e, a, u, c, ,
• Double-check diacritical marks (many African translators omit them)
• UTF-8 encoding mandatory

Apostrophes in Astro JSX Templates (French, Swahili, all languages)

CRITICAL: Single-quoted JS strings inside Astro JSX expressions (.astro template section) CANNOT contain straight apostrophes ('). This breaks the build because the apostrophe terminates the string early.

Rules for any text containing apostrophes (e.g. French d', l', n', qu'; Swahili ng'):

1. Use double-quoted strings for any JS string literal that contains an apostrophe: "d'excellence" not 'd\'excellence'
2. Never use \u2019 escape sequences Astro's template compiler may not handle them correctly
3. Never use backslash-escaped apostrophes (\') in JSX template expressions they work in frontmatter JS but fail in template JSX
4. HTML text content is fine apostrophes in regular HTML <p>d'excellence</p> work without escaping
5. For JSX expression strings that need both " and ', use template literals: `string with ' and "`

Verb Conjugation

• Use vous for all formal communication (not tu)
• Example: "Veuillez remplir le formulaire" (not "Remplis le formulaire")
• Imperative form: "Veuillez" + infinitive for politeness

Kiswahili CTAs and Button Text

Inputs

Evidence Produced

Capability Contract

Review defaults to read-only. Edit only when authorised. Do not change facts, commitments, legal or financial effect, quoted speech, or approved claims in translation. Publishing, certified translation, and external messaging require explicit authority and an appropriate in-country professional reviewer.

Degraded Mode

If a native reviewer, country context, terminology source, or source meaning is unavailable, return the narrowest qualified draft and query list. Mark affected segments not assessed; never claim native or certified quality from automated review alone.

Decision Rules

Workflow

1. Confirm source, target language, country, audience, purpose, channel, voice, and approval route.
2. Extract protected facts, names, numbers, citations, terminology, and non-translatable elements.
3. Select the appropriate register and glossary; stop where source meaning or a regulated term is unresolved.
4. Draft for meaning and natural syntax, then check completeness segment by segment.
5. Verify names, figures, dates, quotations, links, legal and financial meaning, and calls to action.
6. Run language-specific, cultural, accessibility, and anti-slop checks.
7. Recover by reverting meaning-changing edits and raising a query to the source owner or in-country reviewer.
8. Release only with reviewer status and unresolved terminology visible.

Quality Standards

The target text must preserve meaning and consequence while reading naturally for the named country and audience. French and Kiswahili publication requires competent in-country review; regulated content also requires subject review.

Anti-Patterns

• Translating word for word. Fix: translate the sentence's intent and verify meaning against the source.
• Using one Kiswahili or French register for every country. Fix: record target country and obtain local review.
• Translating names, figures, or citations from memory. Fix: copy and verify them against the source.
• Replacing a regulated term with a smoother synonym. Fix: preserve it and ask the subject owner.
• Calling machine output native or certified. Fix: state review status and require a qualified human.
• Improving style by adding unsupported claims. Fix: preserve the source claim boundary.

Worked Example

If a French draft contains a tax term with two plausible translations, retain the source term in the query record, use the provisional term consistently, and block publication until the relevant country and tax reviewer confirms it.
