用法筆記

The direct object is typically time, effort, energy, emotion, or other non-financial resources. Unlike the financial sense, the person or thing that benefits cannot be the direct object — you invest time in a child, not invest a child with time.

常見錯誤

❌I invested three hours to finish the report.
✅I invested three hours in finishing the report.
💡Use in + V-ing, not to + infinitive after invest + time.
❌She invested hard work on the project.
✅She invested hard work in the project.
💡The preposition is in, not on.
❌He invested me with his valuable advice.
✅He invested time in giving me valuable advice.
💡A person cannot be the direct object in this sense; the resource is the object.

    legal term; to give a right or power that is permanent or unconditional

文法句型

invest + [person] + with + [power/authority]

be invested with + [title/quality]

invest + [person] + in/into + [office]

用法筆記

Almost always followed by with + the power, authority, or quality being given. The passive construction (be invested with) is very common, especially in formal or legal writing. Unlike senses 1 and 2, the direct object here is the person receiving something, not the resource.

常見錯誤

❌The manager invested him with a new computer.
✅The manager invested him with the authority to approve purchases.
💡Invest with means giving power or rights, not physical objects.
❌She invested the title of director to him.
✅She invested him with the title of director.
💡Use invest + person + with + title, not invest + title + to + person.
❌The king invested him as a knight in the ceremony.
✅The king invested him with the rank of knight in the ceremony.
💡The formal pattern is invest + person + with + [rank/authority], though invest + person + as + [role] is sometimes used in modern English.
