Conditionals deal with situations and their possible or intended outcomes. They are complex structures in English that contain two clauses made up of a condition and the result if and when that condition is true. Zero, first, second, and third conditionals are useful to say how true or likely or possible something is. Mixed conditionals deal with mixed time-frames and likelihoods combined in one sentence.
This story shows how we can use conditionals to talk about how likely things are in the future and how things might have been different.
