Zero conditional

ZERO CONDITIONAL

Structure of the Conditional Zero

If + sujeto + present simple, sujeto + present simple

The order of the two sentences that make up the structure of the

conditional can be changed. If we start with the condition (If), we will

separate them with a comma. If we start with the phrase that expresses the

result, it is not necessary to put the comma.
