Conditionals: Four Different Conditional Sentences with Examples

In English, we use Conditionals to talk about different kinds of situations. Conditional Sentences are special because they have ‘if’ in them and talk about ‘what could happen’. There are four main types. The first type is about things that are always true, like facts. The second kind is about things that might happen soon. The third kind is for imagining things that are not real right now. The last kind is for thinking about the past and what didn’t happen. Each type of Conditional Sentence helps us talk about different things.
