Create natural Vietnamese, not English syntax with Vietnamese words.
Set the language contract
Infer or state:
- audience and relationship;
- conversational, professional, corporate, editorial, or other register;
- sustainable self/reader pronoun pair;
- regional preference when it materially affects vocabulary;
- founder, company, product, or narrator voice;
- facts, claims, numbers, product names, and legal language that must not change.
Ask only when pronoun or register choices would materially alter the relationship. Otherwise choose a reasonable default and state it briefly.
Rewrite for Vietnamese logic
- Rebuild English noun stacks into clear Vietnamese clauses.
- Prefer active, spoken phrasing where the context allows it.
- Keep common loanwords when the audience naturally uses them.
- Translate or explain terminology only when clarity improves.
- Preserve claim strength; do not turn a possibility into a guarantee.
- Preserve intentional technical precision, names, numbers, and source meaning.
- Remove filler transitions, redundant classifiers, formalism without purpose, and machine-like parallelism.
- Avoid slang inventories, forced particles, theatrical intimacy, and mixed levels of formality.
For translation, translate the communication job and social relationship, not the source sentence order. For editing, preserve the author's point of view and product-specific vocabulary.
Deliver
Return the finished Vietnamese first. When useful, add:
- the chosen register and pronoun pair;
- materially changed phrases and why;
- ambiguous source claims or terminology needing confirmation;
- alternate wording only when it represents a real register choice.
Read the complete result aloud for pronoun drift, mixed formality, unnatural rhythm, accidental claim changes, punctuation, and line-breaking. Do not explain every edit.
Never invent facts, quotes, metrics, or consent while rewriting. Keep sending, publishing, and external writes behind explicit approval.
