Understanding the passive infinitive is a key part of mastering English grammar. Here's a breakdown of its structure and usage:
What is a Passive Infinitive?
- A passive infinitive is an infinitive verb form that indicates the subject of the sentence receives the action, rather than performing it.
Structure:
- The basic structure is: "to be" + past participle.
- Examples:
- "to be seen"
- "to be helped"
- "to be chosen"
- Examples:
Usage:
- Focus on the Receiver:
- The passive infinitive is used when the focus is on the person or thing that is acted upon.
- Example: "She wants to be invited to the party." (The focus is on "she" receiving the invitation.)
- After Modal Verbs:
- It is very common to find passive infinitives following modal verbs.
- Examples:
- "This report should be reviewed." (This could also be written "This report should to be reviewed" but more commonly the "to" is dropped after modal verbs)
- "The documents must be signed."
- After Certain Verbs and Adjectives:
- Passive infinitives are also used after certain verbs and adjectives that express a need, desire, or possibility.
- Examples:
- "The room needs to be cleaned."
- "It is important to be informed."
Key Points:
- The passive infinitive allows us to shift the emphasis of a sentence from the doer of the action to the receiver.
- It's a valuable tool for expressing ideas in a more nuanced way.
