Conditionals Summary: Zero, First, Second, Third Conditionals

Conditional sentences are used to express that one action depends on another. There are four main types of conditionals in English.

Zero Conditional — General Truths

If + Present Simple → Present Simple

Used for facts and general truths.

• If you heat ice, it melts.
• If it rains, the ground gets wet.

First Conditional — Real Possibilities

If + Present Simple → Will + Verb

Used for possible future situations.

• If she arrives early, we will see her.

Second Conditional — Unreal Present

If + Past Simple → Would + Verb

Used for hypothetical or unlikely situations in the present or future.

• If I had a million dollars, I would travel the world.

Third Conditional — Past Regrets

If + Past Perfect → Would Have + Past Participle

Used for unreal situations in the past (impossible to change).

• If I had studied, I would have passed the exam.
• If we had left earlier, we would have caught the train.

Mixed Conditionals

Sometimes we mix the second and third conditionals: If I had studied (past), I would be rich now (present).
