Passive Voice with Modal Verbs with Rules and Examples

Passive voice and modal verbs are two essential aspects of English grammar, each serving a unique purpose. Modal verbs are auxiliary verbs that express certainty, possibility, permission, or obligation in a sentence. On the other hand, the passive voice is a grammatical construction in which the subject receives the action rather than performing it. In this article, we’ll explore how modal verbs and passive voice work together to create different sentence structures. We’ll also share rules and examples to enhance your understanding of this concept. So, let’s get started!

What is Passive Voice?

Passive voice is a way of constructing sentences where the subject of the sentence receives the action of the verb rather than performing it. In passive voice, the focus is on the receiver of the action rather than the doer. For example, “The ball was kicked by Sarah.” In this sentence, the ball (the receiver) is the focus, even though Sarah (the doer) is mentioned.

Structure: Subject + (to be) + past participle + (by + agent, if mentioned)

Passive voice is formed by using a form of the verb “to be” (such as “is,” “am,” “are,” “was,” “were,” etc.) followed by the past participle form of the main verb. It’s often used when the doer of the action is unknown, or unimportant, or when the focus needs to be shifted to the receiver of the action.

What are Modal Verbs?

Modal verbs are a category of auxiliary verbs (also called helping verbs) that express the mood or attitude of the speaker toward the action or state of the main verb in a sentence. These verbs indicate possibility, necessity, permission, ability, obligation, or likelihood. In English, the most common modal verbs include:

• Can: Shows ability or possibility.
• Could: Often used for past ability or polite requests.
• May: Expresses permission or possibility.
• Might: Indicates a possibility, often with uncertainty.
• Must: Shows necessity or strong obligation.
• Shall: Used for making suggestions, promises, or offers.
• Should: Indicates advice, obligation, or expectation.
• Will: Shows future intention or prediction.
• Would: Used for polite requests or hypothetical situations.
• Ought to: Used to express moral obligation or duty.

Passive Voice with Modal Verbs Rules

When combining passive voice with modal verbs, the modal verb appears before the main verb in its past participle form.

Modal + Be + Past Participle

Use a modal verb (can, should, must, might, will, could) followed by a form of the verb “to be” (am, is, are, was, were) and the past participle of the main verb.

• Structure: $ModalVerb+\; be\; (am/is/are/was/were)+past\; participle$
• Examples:
  • The problem can be solved.
  • The document may be misplaced.
  • The solution should be considered.

Modal + Have Been + Past Participle

This structure is used to talk about actions that were completed or ongoing at a specific time in the past.

• Structure: $ModalVerb$ + $havebeen$ + $Past\; Participle$
• Examples:
  • The problem can have been solved.
  • The document may have been misplaced.
  • The solution should have been implemented.

These structures allow us to express various ideas such as possibility, necessity, permission, etc., in passive voice. The first structure emphasizes actions that can happen, are expected, or are allowed to happen, while the second structure highlights actions that likely happened or were ongoing in the past.
