The conditional tense

The conditional tense is used to express actions or events that depend on certain conditions. There are several types of conditional sentences, each serving a different purpose. Below is an explanation of the key types of conditionals, along with examples and exercises to help you understand and practice them.

Types of Conditional Sentences

1. Zero Conditional (Real Condition)

• Form: If + present simple, present simple

• Use: Describes general truths, facts, or situations that are always true.

Example:

• If you heat water to 100°C, it boils.

2. First Conditional (Real Future Condition)

• Form: If + present simple, will + base verb

• Use: Describes a real possibility or situation in the future that is likely to happen if a certain condition is met.

Example:

• If it rains tomorrow, I will bring an umbrella.

3. Second Conditional (Unreal Present or Future Condition)

• Form: If + past simple, would + base verb

• Use: Describes an unreal or hypothetical situation in the present or future, something that is unlikely or impossible.

Example:

• If I were rich, I would travel around the world. (Note: "were" is used for all subjects in hypothetical situations.)

4. Third Conditional (Unreal Past Condition)

• Form: If + past perfect, would have + past participle

• Use: Describes a past situation that did not happen, often used for regrets or to imagine different outcomes.

Example:

• If I had studied harder, I would have passed the exam.

5. Mixed Conditional (Combination of Second and Third)

• Form: If + past perfect, would + base verb (or other combinations)

• Use: Describes a situation where the condition in the past has an effect on the present or future.

Example:

• If I had taken that job, I would be living in New York now. (Past action affecting the present.)
