Every Conditional has two clauses: The conditional (if) clause, and the result clause.
We make a zero conditional sentence using two simple present verbs: one in the ‘conditional clause’ and one in the ‘result clause’.
If + present simple, present simple.
Present simple if present simple.
This conditional is used when the result always happens. So,if it rains, the grass gets wet. It’s a fact. This is in general, not one particular situation.
The ‘if’ in this conditional can usually be replaced by ‘when’ without changing the meaning.
So, When it rains, the grass gets wet. Still true, right?
If it rains, the grass gets wet. It is always true!.
