What Is Voice in English Grammar?
Voice describes the relationship between the subject and the action (verb).
There are two types:
- Active Voice
- Passive Voice
The difference depends on who performs the action.
What Is Active Voice?
In active voice, the subject performs the action.
Structure:
Subject + Verb + Object
Examples:
- Sarah wrote the report.
- The teacher explained the lesson.
- My brother repaired the bicycle.
- They built a new bridge.
The subject is doing the action.
What Is Passive Voice?
In passive voice, the subject receives the action.
Structure:
Subject + Be Verb + Past Participle (+ by + Agent)
Examples:
- The report was written by Sarah.
- The lesson was explained by the teacher.
- The bicycle was repaired by my brother.
- A new bridge was built by them.
The focus is on the object rather than the person performing the action.
