What is the Zero Conditional?
The Zero Conditional expresses things that are always true – universal facts, scientific laws, and automatic results. It uses present simple in both parts of the sentence, connected by 'if', 'when', or 'whenever'.
Structure and Formation
If/When/Whenever + Present Simple, Present Simple
