testify to [noun phrase]

用法筆記

Only used in the pattern 'testify to + noun phrase'. The subject must be a thing (fact, event, object, action) — never a person. This sense cannot be followed by a that-clause.

常見錯誤

❌The facts testify that the system works.
✅The facts testify to the effectiveness of the system.
💡This sense takes 'to + noun phrase', not a that-clause.
