文法句型

[noun] remains undecided

[noun] is still undecided

用法筆記

Subject is always a thing, event, or outcome — never a person. Common in news and formal contexts when reporting on ongoing processes (elections, legal cases, negotiations). Unlike 'pending', which implies a decision is awaited, 'undecided' simply states the absence of a result.

常見錯誤

❌The judge is undecided on the case.' (when meaning the outcome is unresolved)
✅The outcome of the case is undecided.

❌The meeting time is undecided.
✅The meeting time has not been decided yet.
💡'undecided' works, but 'not decided' sounds more natural for simple scheduling.
