What is the zero conditional?
The Zero Conditional is used to talk about general truths, scientific facts, and situations that are always true when the condition is met. This conditional helps us discuss facts that remain the same, regardless of time.
Example Sentences:
- If water reaches 100°C, it boils.
- If you mix red and blue, you get purple.
The outcomes are universally true in these cases, making the Zero Conditional ideal for describing rules and certainties. The zero conditional uses if or when and must be followed by the simple present or imperative.
Forming the Zero Conditional
The structure of the Zero Conditional is simple and consistent. Here’s the formula:
Alternative Form: Simple Present + if + Simple Present
Form: If + Simple Present, Simple Present
EXAMPLE:
When you go to the park, take your ball. (imperative)
When you press the button, the doorbell rings.
The doorbell rings if you press the button.
Using the Zero Conditional in Everyday Language
Here’s how we commonly use the Zero Conditional:
- To state facts and rules: If you touch fire, it burns.
- To explain habits: If I don’t set an alarm, I oversleep.
- To describe scientific truths: If iron rusts, it turns brown.
