Conditionals in English

If you're learning English, you've probably encountered conditionals. These grammatical structures allow us to express hypothetical, imaginary or possible situations in the future. In this article, we present you a complete guide to understanding and mastering conditionals in English.

Types of conditionals

There are four types of conditionals in English, each with its own rules and uses:

First conditional (Conditional 1)

The first conditional is used to talk about possible situations in the future. The structure is as follows:

If + Present Simple, Future Simple (will)

Second conditional (Conditional 2)

The second conditional is used to talk about hypothetical or improbable situations in the present or future. The structure is:

If + Past Simple, would + verb (base form)

Third conditional (Conditional 3)

The third conditional is used to talk about hypothetical situations in the past that did not occur. The structure is:

If + Past Perfect, would have + past participle

Zero Conditional

The conditional zero is used to express universal truths or facts that always occur. The structure is:

If + Present Simple, Present Simple

Uses and examples of conditionals

Let's see examples of each type of conditional:

First conditional

We use the first conditional to talk about possible situations in the future:

• If it rains tomorrow, we will stay at home. (If it rains tomorrow, we will stay home.)

Second conditional

The second conditional is for hypothetical situations in the present or future:

• If I won the lottery, I would buy a house. (If I won the lottery, I would buy a house.)

Third conditional

The third conditional is used for hypothetical situations in the past that did not occur:

• If she had studied hard, she would have passed the exam. (If she had studied more, she would have passed the exam.)

Conditional zero

The conditional zero is used to express universal truths or facts that always occur:

• If you heat water to 100 degrees Celsius, it boils. (If you heat water to 100 degrees Celsius, it boils.)

mixed conditional

In some cases, we can mix different types of conditionals to talk about situations that involve both the past and the present. The structure of a mixed conditional is:

If + Past Perfect, would + verb (base form)

Example:

• If I had known you were coming, I would have prepared dinner. (If I had known you were coming, I would have made dinner.)

Common expressions with conditionals

There are some common expressions in English that are often used with conditionals:

1. Unless: It can be used instead of “if…not” in conditionals.

• We won't go to the park unless it stops raining. (We won't go to the park unless it stops raining.)

2. In case: Used to express precautions or actions taken in a possible situation.

• I'll bring an umbrella in case it rains. (I'll take an umbrella in case it rains.)

3. As long as: Indicates a necessary condition for something to happen.

• You can use my car as long as you return it before 8.

Common mistakes in using conditionals

When learning conditionals in English, it is common to make some mistakes. These are some of the most frequent:

1. Confuse the use of "will" and "would" in conditional sentences.
2. Use the past simple instead of the past perfect in the third conditional.
3. Forget the basic structure of each conditional.
