Meaning and Usage
The canonical token “sister” maps to the Chinese unit “姐姐” in the approved Year 1 Home and Family context. This page treats the token as a concrete or conceptual noun that can occupy a subject or object position. The mapping is deliberately narrower than a general bilingual dictionary entry: it records the Chinese semantic unit that a learner can trace through a Chinglish sentence, then compares that trace with natural English. Use the token when the source Chinese expresses this approved sense directly. Keep the base token stable even when natural English would add an article, change word order, mark number, or inflect a verb. Those English grammar changes belong to the Natural English comparison layer and do not alter the canonical mapping. The Week 5 editorial context supplies the page’s examples and relations, but it does not create a universal translation rule. A different Chinese sense, a figurative use, a specialist meaning, or a context requiring another English word must be reviewed as a separate mapping rather than forced into this profile. Generator use remains disabled until a later Pattern review proves that the surrounding roles and semantic constraints are sufficiently precise.
Mapping Boundary
Correct Use: Use sister when the source unit is 姐姐 in the approved context.
Incorrect Use: Do not use sister as a universal replacement for every related Chinese or English sense.
Reason: The canonical mapping is contextual and must preserve the reviewed Chinese semantic unit.
