What is the conditional?

The conditional is used in general to express what could happen, what might have happened, and what we wish would happen.

The formula of the sentence : conditional clause or if clause + main clause and we do remove the comma if the position is changed for the main and conditional clause but the important thing in conditional is the verb tenses.
