Conditionals are sentences that describe real or hypothetical situations and their possible outcomes. They often follow an “if… then” structure and are used to express facts, possibilities, regrets, or imaginary scenarios. Mastering conditionals is essential for clear and precise communication.

1. Types of Conditionals

A. Zero Conditional (General Truths or Scientific Facts)

Use: Describes situations that are always true, such as facts or general truths.
Structure: If + present simple, present simple.
Example: “If you heat water to 100°C, it boils.”

If-Clause	Main Clause
If you heat water to 100°C,	it boils.
If it rains,	the ground gets wet.

B. First Conditional (Real and Possible Situations)

Use: Describes real and possible situations in the future.
Structure: If + present simple, will + base verb.
Example: “If it rains tomorrow, we will cancel the picnic.”

If-Clause	Main Clause
If it rains tomorrow,	we will cancel the picnic.
If I see him,	I will talk to him.

C. Second Conditional (Unreal or Hypothetical Situations)

Use: Describes hypothetical or unlikely situations in the present or future.
Structure: If + past simple, would + base verb.
Example: “If I won the lottery, I would travel around the world.”

If-Clause	Main Clause
If I won the lottery,	I would travel the world.
If I were rich,	I would buy a mansion.

D. Third Conditional (Regrets or Past Hypotheticals)

Use: Describes past situations that didn’t happen, often expressing regret or reflection.
Structure: If + past perfect, would have + past participle.
Example: “If I had studied harder, I would have passed the exam.”

If-Clause	Main Clause
If I had studied harder,	I would have passed the exam.
If she had known,	she would have helped.

E. Mixed Conditional (Combination of Past and Present/Future)

Use: Combines elements of second and third conditionals to describe how past events affect the present or how present conditions would have affected the past.
Structure 1: If + past perfect, would + base verb.
(Past event affecting the present.)
Structure 2: If + past simple, would have + past participle.
(Present condition affecting the past.)
Example:
- “If I had studied harder, I would be in a better job now.”
- “If I were richer, I would have bought that house.”

If-Clause	Main Clause
If I had studied harder,	I would be in a better job now.
If I were richer,	I would have bought that house.
