Key Concepts & Vocabulary
TermDefinitionExample
VoiceThe form of a verb that indicates whether the grammatical subject performs the action (active) or receives the action (passive).Active: 'The author *writes* the novel.' Passive: 'The novel *is written* by the author.'
Active VoiceA sentence structure where the subject performs the action of the verb.'Macbeth murders King Duncan.' (The subject, Macbeth, performs the action, murders).

Key Rules & Conventions
Active Voice Formula
Subject (Doer) + Action Verb + Object (Receiver)
Use this formula to construct or identify a standard active voice sentence. The focus is clearly on the subject performing the action.
Passive Voice Formula
Subject (Receiver) + Verb 'to be' (am, is, are, was, were) + Past Participle + (optional 'by' phrase with Agent/Doer)
This is the key pattern for identifying passive voice. Look for a form of the verb 'to be' immediately followed by a past participle.
The 'Doer' Test
Ask: 'Who or what is performing the action of the main verb?'
If the answer is the grammatical subject of the sentence, the voice is active. If the subject is having the action done to it, the voice is passive.

Challenging
A student's essay argues that a corporation is avoiding blame. The student writes: 'Mistakes were made, and the safety regulations were ignored.' Why is the use of passive voice particularly effective for this argument?
