Active Voice

Use the active voice

At the heart of every good sentence is a strong, precise verb; the converse is true as well--at the core of most confusing, awkward, or wordy sentences lies a weak verb.

Try to use the active voice whenever possible.

Active vs. passive voice

In a sentence written in the active voice, the subject of sentence performs the action. In a sentence written in the passive voice the subject receives the action.

Active: The candidate believes that Congress must place a ceiling on the budget.

Passive: It is believed by the candidate that a ceiling must be placed on the budget by Congress.

Active: Researchers earlier showed that high stress can cause heart attacks.

Passive: It was earlier demonstrated that heart attacks can be caused by high stress.

Active: The dog bit the man.

Passive: The man was bitten by the dog.

Converting sentences to active voice

Here are some tips and strategies for converting sentences from the passive to the active voice.

• Look for a "by" phrase (e.g., "by the dog" in the last example above). If you find one, the sentence may be in the passive voice. Rewrite the sentence so that the subject buried in the "by" clause is closer to the beginning of the sentence.

• If the subject of the sentence is somewhat anonymous, see if you can use a general term, such as "researchers," or "the study," or "experts in this field."

When to use passive voice

There are sometimes good reasons to use the passive voice.

To emphasize the action rather than the actor

After long debate, the proposal was endorsed by the long-range planning committee.

To keep the subject and focus consistent throughout a passage

The data processing department recently presented what proved to be a controversial proposal to expand its staff. After long debate, the proposal was endorsed by . . . .

To be tactful by not naming the actor

The procedures were somehow misinterpreted.

To describe a condition in which the actor is unknown or unimportant

Every year, thousands of people are diagnosed as having cancer.

To create an authoritative tone

Visitors are not allowed after 9:00 p.m.

Active Voice, Passive Voice

There are two special forms for verbs called voice:

1. Active voice

2. Passive voice

The active voice is the "normal" voice. This is the voice that we use most of the time. You are probably already familiar with the active voice. In the active voice, the object receives the action of the verb:

active subject verb object

>

Cats eat fish.

The passive voice is less usual. In the passive voice, the subject receives the action of the verb:

passive subject verb object

<

Fish are eaten by cats.

The object of the active verb becomes the subject of the passive verb:

subject verb object

active Everybody drinks water.

passive Water is drunk by everybody.

Definition

Active voice is a voice that indicates a subject has the semantic function of actor.

Example (English)

• The following sentence construction is in active voice. The subject Jones has the semantic function of actor.

• Jones built the house.

The above active construction contrasts with the following construction in passive voice, where Jones has the semantic function of actor but house is the subject:

• The house was built by Jones.

• actor

• patient, or

• recipient.

Examples (English)

• The following sentence is in active voice:

• Jones built the house.

The following sentence is in passive voice:

• The house was built by Jones.

Use of Passive

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.

Example: My bike was stolen.

In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.

Sometimes a statement in passive is more polite than active voice, as the following example shows:

Example: A mistake was made.

In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).

Form of Passive

Subject + finite form of to be + Past Participle (3rd column of irregular verbs)

Example: A letter was written.

When rewriting active sentences in passive voice, note the following:

• the object
