This document discusses different types of conditionals in English grammar: zero, one, two, three, and mixed conditionals. It provides the structure and examples of each type of conditional. Zero conditionals are used to express universal truths or facts and have the structure of "if + present + present". First conditionals are used for predictions or possibilities and have the structure of "if + present + future". Second conditionals express unlikely or hypothetical situations with the structure "if + past + conditional". Third conditionals refer to regrets about past situations and use "if + past perfect + conditional perfect". Mixed conditionals combine elements of the third conditional with results in the present.
