1. ACTIVE & PASSIVE VOICE
Understanding Active and
Passive Voice

SIR ABDUL HAMEED KALOI

2. What is voice?
• A form or set of forms of a verb showing
the relation of the subject to the action.
• Note: vice means moral fault or
weakness.
• As a prefix it means a title as Vice
Principal, Vice captain etc=et cetera.

3. Verbs and Voice
• Voice is the form a verb takes to
indicate whether the subject of the
verb performs or receives the
action.
• There are two types of voice:
active voice and passive voice.

4. Active Voice
• Active voice verbs are used when the subject
is acting in a sentence.
Doer + Action + Receiver of action
• Example:
– Sir Imran teaches Physics .
• “Teach” is an active verb because it allows the
subject to undertake an action.

5. Passive Voice
• “Passive voice” verbs are used when the subject
is being acted upon in a sentence.
Example:
– Physics is taught by Sir Imran.
• “Is taught” are considered passive because they
indicate that the subject (Physics) is receiving
an action.

6. So What?
• Although both constructions are grammatically
correct, the active voice is usually more effective in
academic and business writing because it is simpler
and more direct.
• The passive construction is effective only when the
doer of the action is unknown.
Examples:
– The house was built.
– The ball was hit.
– Smoking is prohibited .

7. Subject Pronoun change into Object as
He into him
She into her
They into them
We into us
I into me
You into you
It into it
Name remains same.
