Understanding Active and Passive Voice

Have you ever wondered why some sentences say “The teacher praised the student” while others say “The student was praised by the teacher”? Both sentences mean the same thing, but they’re written in different voices. These are called the 'active voice' and the 'passive voice'. Understanding these two forms will help you write and speak English more clearly and naturally. Let’s explore them step by step!

👉 What Is the Active Voice?

In an active voice sentence, the subject does the action. The focus is on who or what is doing the action.

Structure: Subject + Verb + Object

Examples:

The teacher explained the lesson.

My mother bakes delicious cakes.

The dog chased the cat.

In each example, the subject (teacher, mother, dog) performs the action. Active voice is direct, clear, and easy to understand. That’s why it’s often used in everyday speaking and writing.

👉 What Is the Passive Voice?

In a passive voice sentence, the subject receives the action instead of doing it. The focus is on what happens or who the action is done to.

Structure: Object + Form of “be” + Past Participle + by + Subject

Examples:

The lesson was explained by the teacher.

Delicious cakes are baked by my mother.

The cat was chased by the dog.

In these sentences, the subject (lesson, cakes, cat) is not doing the action, it is receiving it. Passive voice is often used when the doer of the action is unknown, unimportant, or when we want to emphasise the result instead of the person.

👉 How to Change from Active to Passive?

Let’s look at a few examples of how we can turn an active sentence into a passive one.

    1. (a) Active: The chef cooked the meal.

        (b) Passive: The meal was cooked by the chef.

    2. (a) Active: The company will launch a new product.

        (b) Passive: A new product will be launched by the company.

    3. (a) Active: The students are writing essays.

        (b) Passive: Essays are being written by the students.

👉Tips:

1. Move the object of the active sentence to the subject position.

2. Use the correct form of “be” (am, is, are, was, were, been, being).

3. Change the main verb into its past participle form.

4. Add “by + doer” if you want to mention who did the action.
