What is a conditional sentence?
A conditional sentence expresses a relationship between a condition and a result. It has an if-clause and a main clause. English has six main types, each expressing a different degree of reality or time reference. This lesson also covers conditional questions and conditional inversion — formal alternatives to "if" structures.
